Thank you for using "PostHistory."
Here you will find setup instructions, frequently asked questions (FAQ), and contact information for this app.
To automatically log your post history, initial setup in Safari is required:
Open the Settings app on your iPhone / iPad.
Go to Safari > Extensions.
Tap PostHistory and toggle the switch to On.
Under the permissions section at the bottom, set access for x.com (or twitter.com) to Always Allow.
Open [https://x.com](https://x.com) in Safari and browse posts; your viewing history will automatically save to the app.
Note: You can toggle "Auto Record" on or off at any time via the puzzle piece icon (Extensions menu) in the Safari toolbar.
Please verify that the Safari extension is toggled "On" and that website access for x.com is set to "Always Allow."
History logging works when browsing the web version of X (x.com) via the Safari browser (browsing inside the official X app is not supported).
If you use Private Browsing mode, you may need to enable extension permissions for Private Browsing within Safari's settings.
No, absolutely not.
PostHistory is designed to run entirely locally. All retrieved post text, images, and timestamps are saved solely on your device (local storage / SQLite). There is zero data tracking, collection, or transmission to external servers.
Go to the Settings tab > Delete section in the app:
"Delete Non-Favorited History": Clears all history except posts you have marked as favorites/bookmarks.
"Clear All Browsing History": Resets and erases all data stored locally on your device.
Because data is stored in a local database on your device, deleting the app will permanently remove all saved history. If needed, please export a backup via Settings > Export Data in JSON or CSV format beforehand.
