## What is PostHistory for X?

Have you ever been reading an interesting post on X, only for the timeline to suddenly refresh and make it disappear forever?

PostHistory solves this frustration once and for all. By enabling the lightweight Safari Web Extension, every post you scroll past on x.com in Safari is automatically saved to your personal, on-device history log.

Even if you forgot to hit Like or Bookmark, you can instantly search and find any post you viewed later.


KEY FEATURES

• Automatic Browsing History
Just browse x.com in Safari as usual. Posts that appear on your screen are automatically recorded in the background — no manual bookmarking required.

• 100% On-Device Privacy (Zero External Servers)
Your browsing history is yours alone. All data is stored exclusively inside your iPhone's local SQLite database. Nothing is ever uploaded to external servers, cloud databases, or analytics trackers. No account login or API connection is required.

• Instant Full-Text & Media Search
Quickly find "that post I saw earlier" by keyword, author name, or @handle. Filter your history by Today, Favorites, Images, Videos, or Article links with a single tap.

• App-Like Safari UI Optimization
Enjoy a cleaner mobile web experience on Safari. The extension automatically hides intrusive "Open in App" popups and optimizes the bottom navigation bar for iPhone.

• Organize with Favorites & Custom Tags
Heart your favorite posts to protect them from auto-cleanup, and organize them into custom tags like folders (e.g., "AI & Tech", "Read Later", "Recipes").

• Export Your Data Anytime
Export your saved history to JSON or CSV format anytime for personal backups or spreadsheets.


POSTHISTORY PRO (OPTIONAL UPGRADE)

PostHistory is free to use (stores up to your latest 100 viewed posts, with favorited posts always protected). Upgrade to PostHistory Pro to unlock:

• Unlimited History Storage: Remove the 100-post limit and keep tens of thousands of posts forever.
• Auto-Filter Promoted Posts: Automatically filter out promoted posts from your timeline and saved history.
• Smart Recording Controls: Choose to save media-only posts, skip reposts (RTs), or mute specific keywords and accounts.
• Calendar & Date Range Search: Jump back to any specific date or period using the interactive calendar.

Available Plans (US):
• Monthly Plan: $0.99 / month
• Annual Plan: $6.99 / year
• Lifetime License: $11.99 (One-time purchase)
