This Dash web app uses the Mastodon API to scan your bookmarks and favorites for links (specifically the card attribute which I believe is created when a link preview is generated.)
It should successfully redirect to your instance and back with an access_token. All tokens/codes etc are stored in browser local storage but encrypted with Fernet so no other site should be able to do much with them should they somehow access the local storage values. It requests only read-only access.
TODO:
* Hide/Show the Login/Authorize interface
- Add manual refresh button
- Limit lookback window by time (i.e. only 30 days, rather than 40 posts)
- Setting for how far back / how many bookmarks/faves to use. (settings tab?)
- About / FAQ tab
- Include boosts as an option?
- Better CSS and layout
