1. Start

1.1 Set Initial Password

When first using PP, it will ask you to set a password for the initial account, tap "Set Password" and input your password and confirm it, tap "Save" button at the top right of screen, and then you see the home screen of PP. (the top-right button on home screen could be used to switch the list between viewing mode and editing mode)
Image

This password (account password) is not only used for unlocking screen, but also used for data encryption and some other security features. For example, while importing data from archived file, it will ask you for a password to validate if you are the owner or not, which must be the same as the account password when you were exporting those data.

1.2 Lock/Unlock the Screen
When you are leaving PP for some reason, such as running other apps, or answering a call, or after you lock your phone, PP will lock it self at the same time, in order to protect your data, and when you come back, PP will ask you for password to unlock.
Image

2. Create And Edit Data

PrivatePal 1.1 does not create any system categories or items when it is initialized. Anyway, you can customize your own categories and hierarchies.

2.1 Create Category (Folder , Tag)

PP supports multi-level categories, and you can use categories as "Tags" in PP, which means you can set a single item belong to multiple categories. This optimized design combines both advantages of Tags and Folders, which provides you a much easier way for organizing huge amounts of items.

To create a category, first, at the home screen, tap the "Edit" button at the top-right corner to start the editing mode, then the "Edit Toolbar" will appear at the bottom of screen:
Image

In "Edit Toolbar", there are four buttons, "Create Category", "Create Item", "Bulk Import Medias" and "Create".
Image

Tap the "Create Category" button, or Tap the "Create" and select the creation type as "Category", both could start creation of a new category.
Image

New category will be created under "current category", by default, current category is the root category, named: "Private Pal". When you've entered a category by tapping it and list all its sub-item, then the "current category" has changed to this category.

Q 2.1.1: What is the usage of "about" property?
Each category and item must have a name, and optionally have the "about" information. The content of "about" could be used as description of an item, which would be displayed with item's name and icon when listing. What's more, the "about" informations could be searched, which means you can add all keywords of an item in its "about" information, and this may help you to find the item much easier when searching (with these keywords).

⬆Back To Index

2.2 Create Sub-Categories

You can create multiple sub-categories for an existing category, like sub-directories, one sub-category could only belong to one parent category.

To create a sub-category, or move a category from one parent to another, you only need to tap the current "Parent Category" in "Edit Category" screen or "Create New Category" screen, and then in the "Choose Category" screen, select a new parent category and tap "Save" button at the top-left.
Image

Attention: A Category could only belong to one single parent, but an item could belong to multiple categories.

Repeat the processes above, you can create up a complex hierarchy of categories of your own.
Image

⬆Back To Index

2.3 Edit / Delete Categories

When the home screen is in editing mode, you can start editing any category in the list by tapping it.
(If it is in viewing mode, tap the category will enter it and list all its sub-items and sub-categories, and set current category as this one).

When editing a category in "Edit Category" screen, the button at bottom of the screen named "Delete Category" could be used to delete this category from its parent and delete all its sub-categories and sub-items. (Attention that if an item belongs not only to one category, it may not be deleted when you just delete one or part of the categories which it belong to.)

You can also delete a category by tapping the delete button when listing in home screen and editing mode is on.

Q 2.3.1: How to enter a category instead of editing it when home screen is in editing mode?
When home screen is in editing mode, tap a category will start editing it instead of open it. To open a category in editing mode, you can use the "Sublist" button at the right of a category, which is colored in orange and has an arrow icon in it.
Image
(Attention that "Sublist" is enabled in display mode of both "Row List" and "Large Icon", but for "Small Icon", since the button has become too small, it is disabled and only be used for identifying whether the element is a category or private item)

Q 2.3.2: How to change the order of sub-items or sub-categories of a category?
First entered "Category View" in home screen by tapping the "Category View" tab button, and start editing mode by tap the top-right "Editing" button, then make sure the display mode is "Row List" (small icon and large icon list do not support re-ordering feature currently), then tap and drag the "re-order" button at the right side of an element (see picture in Q 2.3.1). You may drag it up and down to change the order to a proper place.
Attention that although PP supports display a list as "Small Icons" or "Large Icons", currently it is not supported for dragging those icons.

2.4 Create/Edit/Delete Items

【Create An Item】[/b]

There are many ways to add new private items to PP:
(i) Tap the“Create Item”button Image in "Edit Toolbar".
(ii) Tap the "Create" button Image in "Edit Toolbar", and choose a type/template for item to create.
(iii) Tap “Bulk Import Medias” button Image in "Edit Toolbar", and select multiple medias from album and import.
(iv) Use importing feature to import all newly created or updated items from an archived file from earlier backup or other device.
(v) Use“Create Format Copy” feature to create an item with same format based on an existing item.

Here we only talk about the first: the "Create Item” button, others would be introduced later.

Tap the "Create Item" to start creating a new item, input name (must) and about information (optional), then tap the "Add New Field" to create a row of content for this item. If you choose to create a row of type "Simple Text", you can set a title and a value for it. You can add as many rows of content as you like to a single item, with different types.
Image

Q 2.4.1: What's the differences between "Simple Text" and "Multi-line Text"?
Multi-line text is preferred to be used for long text which may contain multiple rows, and could be viewed or edited in a separated, full-screen editor, it might be used for protecting SMSs, emails, notes, articles, etc.
"Simple Text" is preferred to be used for short text which you may want special operations on them. For example, you may want to call it if it is a phone number, or visit the website if it is a URL address, or send an email to it if it is an email address. All those types of text will be automatically detected by PP and it will show the proper operation in a pop up menu when tapping the content.
Image

An private item could belong to multiple categories, For example, a photo could belong to both "My Friends" category and "Bicycle Travel" category at the same time. PP supports setting multiple categories for a single item, after doing that, you can find the photo under both categories.

To edit categories of an item, first tap any of the current category name in editing screen of an item ("Create New Item" screen or "Edit Item" screen), then you will see the "Choose Category" screen, select one or multiple categories by tap it in the list, or re-tap it to deselect, then tap "Save" button at top-right to confirm the selection and back to editing screen. What's more, the triangle button left to the category name could be used to fold/unfold a category with sub-categories.
Image

When all editing have been done, tap the "Save" button at top-right corner of editing screen to save the new item and quit the screen.
Image

【Edit An Item】

There are two ways to start editing of an existing item:
(1): When home screen is in editing mode, tap an item in the list to start editing it directly. At this time, the top-left button on navigation bar is use to "back to home screen without save" and top-right button is to "save and back to home screen".
(2): When home screen is in viewing mode, tap an item to start viewing it, and then tap the top-right button to start editing. At this time, the top-left button on navigation bar is used to "undo editing and back to viewing" and top-right button is used to "save and back to viewing".
Image

【Delete An Item】

When home screen is in editing mode, tap the delete button of an item could delete it. Or in the "Edit Item" screen, tap the "Delete Item" button at the bottom of screen could also delete it.
Attention that if you are deleting an item using delete button in home screen editing mode, and if the current list is "Category View", then you've only deleted the item from "current category", if the item belongs to multiple categories, you may still find them under those categories. Anyway, if you are deleting an item from Favorites list, Search Result list, Recents list, or using delete button in "Edit Item" screen, the item would be totally deleted from all its categories and all its content rows would be deleted at the same time.

2.5 Create Custom Icons

You can customize icons for both categories and items in PP. There are 3 kinds of icons:
(i) System icons.
(ii) Customized icons by cropped photo from iOS photo album. (You may first download original icons from Internet to photo album using Safari)
(iii) Auto-generated thumbnail from media content, such as photos, videos.

To select a system icon, first enter the editing screen of a category or item, tap the icon left to the item name, then in the "Choose Icon" screen, select a system icon as you like.
Image

To create custom icons, tap the "Add Custom Icon" in "Choose Icon" screen, select a photo from the album, and then you can drag or zoom the photo to set the crop region of the icon. After finished, tap "Choose" and the new icon is created. You can use or reuse it later just like system icons.
Image

Attention that the icon quality may be different based on the device, if it is a retina device, the icon size would be 2x2 times to none-retina one.

2.6 Delete Custom Icons

Only custom icons could be deleted, to delete a custom icon, tap the red "Delete" button next to each icon in "Choose Icon" screen.
Image

Attention that if you are deleting an icon that is currently being used, the deletion is allowed and the items that are using this icon will show an empty icon after the deletion. Anyway, it is suggested you not doing this for deleting using icons.

2.7 Get More Icons

Although PP supports custom icon by cropping your saved photos, you may still want more icons for perfectly represent your private items.

To get more icons, you can use Safari to download icons from Google Images search result.

For example, If you need an icon for Facebook, run "Safari", search for "Facebook" or "Facebook logo" in Google Images, and in the results list, long press the image you want to download and tap "Save Image". Now it is in your Saved Photo album which could be used for "Add Custom Icon" in PP.
Image

What's more, Icons in PP are not combined with user account, they could be shared among all accounts. And, you also can export all your icons to a single ppxa file and share it with others.
This article contains 74 beautiful icons for using in PP; (http://duweis.com/forums/viewtopic.php?f=14&t=135.)

Q2.7.1 How to export all icons without my private data.
The Best way for doing this is to create a new account, with no categories or items in it, and then using the "Archive To File" in "Archive/Import" in Settings.
Attention that all "Shared" items and "Shared" categories would also be visible even in new-created empty account, and could be exported with all icons while doing archiving.

2.8 Create And Save Multi-line Text

You can create an item with a row of multi-line text by tapping "Create" button in "Edit Toolbar" in home screen, and then choose the type of "Message" to create, you can also add new row of "multi-line" text to an item by tapping "Add New Field Row" and selecting type of "Multi line Text" in editing screen of an item.

2.9 Add Single Photo/Video From Album

PP supports both single importing or bulk importing for medias from iOS album. You can also take new photo or record new video in PP and save them with protection immediately.

Image

When you are using photo importing for the first time, iOS will alert you that "Private Pal would like to use your current location ...", It is because that PP is reading photo properties which may contains location values. Please tap "OK" to allowed PP to do so, or PP could not read photos from album.
Image

Attention that PP will never read or use any user location data, we promise it. Those warnings are just come from iOS core design, since it can not separate image's location data from other properties, it show that warning just to inform you that location data "might be" read, but not "is being reading" or "has been read". If you've ever used any other apps that need reading photos from iOS album, you may have seen the same alert before.

Q 2.9.1 How to deal with the error of "Failed with errors while adding protection to media files..."?
Image
It may be because of that you have disabled the "Location Service" in iOS Settings, or you have chosen to not allow PP to use Location Service, as we mentioned above, although PP do not need any user location data, you should still allowed PP to use Location Service in order to access photos in iOS album which may contains location data.

When Importing is succeed, all data have been encrypted and saved in PP, you can now delete the original photos or videos in photo albums.

Before PP 1.1, it would reduce the image quality when doing photo importing, but from version 1.1, PP could process any photos or videos with full-resolution. For all files, photos, videos protected in PP, after removes all protections on them, they are exactly the same as they were imported.

In PP, an item would contain multiple fields(rows) of text, photos, videos and files, the item in the following picture contains two photos in a single item.

2.12 Use Auto Thumbnail

Each Item in PP could have an icon, you may choose a system icon for it or customize your own icons from photos in album. You can also choose to "Use Auto Thumbnail" as icon. If an item's icon setting is set to "Use Auto Thumbnail", it will first check if there is any medias fields in this item, if so, it will generate a thumbnail for the first found media field and set it as the thumbnail of the item.
Image

Following picture shows the differences of items' representations in list when using different types of icons.
Image

Attention that Categories could not use auto thumbnail, the "Use Auto Thumbnail" option will be changed to "Do Not Use Icon".

If you found any auto-generated thumbnail is wrong, you can enter the "Choose Icon" screen, and choose "Use Auto Thumbnail" again to manually re-generate the thumbnail.

Thumbnails need disk space for storage, higher quality would use more space, you can change the "settings" named "Thumbnail" to control the size and performance of all thumbnails.

3. Search

PP supports search for all items and categories, for security and performance reasons, PP only searches text in titles and about information. To help finding an item more easily, you can add as many keywords as you can in the "about" information, so that PP could search them out by any of those keywords.

PP also supports Fuzzy Search, which means you do not need to input the exact words or characters but just a part or pattern of them.
To use fuzzy search, you need to use two special characters: the underscore(_) and the percent sign(%). The underscore(_) is used to match a single character, while the percent sign is used to match any characters or text.
Examples:
Suppose there are four items named: "load", "lord", "lode"and "loved"
Search: "lod", would only find : "lode"
Search: "lo_d", would find "load" and "lord", but not for "lode" and "loved".
Search: "lo%d", would find them all.
Fuzzy Search supports all unicode characters, such as Chinese characters.
For example:
Search“西_湖” would find “西子湖”,“西门湖”
Search“西%湖” would find not only "西子湖", "西门湖", but also "西湖" and "西边的湖" , etc.

What's more, If you want search for multiple keywords, please use a percent sign(%) to connect them all. For example, "bike%travel" would search out result contains both "bike" and "travel". (Attention that the keywords order may affect the search results)

Image

Attention: For security reasons, PP do not support any kinds of "password resetting" features or services if you forgot it, so PLEASE BE SURE to remember your account password, or all your data will be locked forever.

⬆Back To Index

6.2 Multi-Account Management

PP supports multi-Account, also the UI for it is very simple, but the logic is quite complicated.

You can create as many accounts as you want for different reasons, each account is separated, transparent and equal to others. No one knows how many accounts totally are there and who create the current account, nor do they know if current account is the top account.

To create new account, just tap the "Create New Account" in settings, and set a password for the new account, and that's all.
Image

The passwords for each of the accounts must be different from each other, PP will give you a warning if you are setting same password as an existing one when creating new account.

For connivence to know how many accounts you have ever created, their will be a number displayed next to the "Create New Account" title, which only indicates how many accounts have been created by "current account", not the totally account of the PP. Through this number, the user of the account you have ever created still do not know if they are the top account or not, since their number of sub-accounts will be zero if they do not create any account under them.

When unlocking the screen with password, PP will lookup all accounts to find the one with the same password as you input, if found, then PP login with the matched account and show its data.

Each account will has its own data, they are totally invisible when users login as other account, but "Shared" items/categories are the exception, they could be seen or edited by all accounts in your PP.

Attention: Custom Icons has no account control, which could be used and edited by all accounts.

Q6.2.1: When need I create new account?
(i) When your family or friends ask you for PP's password, and you do not want to deny them, you can first create a special account for them, with no data or none-sensitive data in it, and share this account password with them.
(ii) When you are afraid that someone may try your password out when get your iPhone or iPad, you can create new account with simple password and empty data for them, such as using password of "1234". when others have tried this simple password and have logged in, they have no idea whether it is the top account or not, and they may stop trying anymore.
(iii) When you and some others are using the same iOS device, such as an iPad sharing with all family members, on which you could install only one PP, but you all want to keep your own data private from each other, and share some common data for all, then you can create accounts for each of the users.

6.3 Set Auto-Lock interval

Each time when you left PP and are coming back to use it again, you may be asked to input the account password to unlock, but sometimes, you may not want to input password so frequently in a period of time, for example, you switch to the other apps to copy text, and switch back to paste it to PP, you may want to skip the password inputing screen in that situation. Then, change the setting of "Auto Lock" interval helps.

"Auto Lock" interval will be judged when PP is active again, if the duration from last time you left PP to the time you active PP is less than the interval, PP will skip locking screen and directly log you in with the last validated account.

For example, if you set the interval to "After 30 minutes", then you do not need to input password to unlock PP within 30 minutes.

6.4 Set Auto-Thumbnail Size

The setting of "Thumbnail" is used to change the auto-generated thumbnail size for items set to "Use Auto Thumbnail".
There are two options:
"Best Performance": generates thumbnails with smaller size, faster speed, but worse display quality.
"Best Quality": generates thumbnails with larger size, slower speed, but higher quality. (Recommended)

6.5 Data Backup and Importing

6.5.1 Data Backup (Export)

PP supports archiving all the data of the current account to a single archived and encrypted file, including the data for custom icons.

To do this, select "Archive/Import" in Settings, then in the "Backup And Import" screen, tap the "Archive To File".

PP's archived data files has the file extension of PPXA (in PP version 1.0, it is PPXT), it may includes all items, categories, custom icons, full-encrypted files, photos and videos, which may make it very large. So it is suggested to delete those old archived files ASAP while you do not need them any more, or when new archived file has been just generated.

What's more, PP's archived file could not be opened by any apps or tools except PP it self, since it is an encrypted and private format with password protection. When doing importing from this file, you need to input the account password of these data. If you've changed your account password, the old files archived before the password change still use the old password for validation, and the new archived file after the password change will need to input the new one to import data in it.

6.5.2 Data importing (Synchronize)

PP can import those archived data from PPXA/PPXT files by selecting the file in "Share File" list in "Backup and Import" screen and choose the action of "Import/Sync File".

You also can copy or move PPXA/PPXT files between different devices in order to do synchronization, or recover data after iOS system was installed or reinstalled.

Attention that PP's importing is not only includes inserting of none-exist data, but also includes updating of existing data if its "last edit time" is earlier than the imported one, and PP will never do deleting synchronization when importing data. Which means your count of data in PP will only be increased or kept the same after the importing.

PP is using a special logic to identify whether two items on different devices are the same one or originally the same, it is not based on titles or any of its content, which means you can change the title or content of an item and synchronize the changes to another device by archive-and-import.

Please Pay much attention to the exporting/importing for multi-accounts situations, There are several rules for doing data transferring when multiple accounts exists. If you break those rules, PP may not work as you wish.

Before those rules, let's have a general idea about the importing logic of PP when multiple accounts exist.
> For data which does not exist in any of the local accounts, PP will insert the data, and if it is not a "Shared" one, PP will change its owner to current account.
> For data which has already existed in one local account, no matter it is current account or not, PP will check its last edit time, if the local data are edited earlier, PP will update the local data, and change its owner to current user. If the local data are edited later than the imported one, PP will do nothing.
This kind of logic is designed for cross-device and cross-account data transfer, but not worked well for all situation.

For example, suppose device 1 has one account of A, device 2 has two accounts of B and C:
When you've first archived account A and imported it to B. It works well and all A's data will be inserted and change the owner as B.
Later, when you've changed some data in A, and archived A again. then, if you login device 2 as C, and tried to import the newly archived data of A to C, there are issues:
For those recently changed data, they will be updated and change their owner to C.
For those unchanged data, PP will do nothing and they are still under account of B.

To avoid this, please do follow two rules for exporting and importing data while dealing with multiple accounts.

Rule 1: For transferring data on same device, never do cross account data importing.
For example: Account A will always imported the data file that is archived from account A.

Rule - 2: For transferring data between different devices, if one account has once imported data from another account from other devices, then it must always import/sync data from that same account.
For example, if account A and account B exist on device 1, and account C exists on device 2, and if C has once imported data from account A, then C should always import data from account A, or export data to account A, never from account B or to account B.

Q 6.5.2.1: How can I transfer data from account A to B on same device?
It is not suggested to do this by archiving and importing, anyway you can do this by: First, login with account A, then set all data you want to transfer to account B as "Shared", then, login as account B, and set all these "Shared" data as "Unshared" by turn off the "Shared" switch.

6.6 Lock Current Screen

The "Lock Private Pal Now" button in settings is used to lock PP immediately even if you have set a Auto Lock interval and the interval has not yet reached.

This manually locking feature could also be used for switch among different accounts. When screen is locked, you can input different password to unlock so that you can login as different account.
