Sequence Diagram privacy policy

Sequence Diagram renders Mermaid sequence text.

Data and use

Chrome extension storage keeps up to 20 diagram sources, titles, themes, timestamps and preferences in sequenceDiagram.v1, and rating-prompt state in sequenceDiagramRatePrompt. SVG embeds source; Copy puts PNG and source on the clipboard.

Analytics

The welcome page opens once after the first installation and sends the install count through this site, which derives the country from the connection and stores nothing. Goodbye and rating pages use analytics to count removals.

Feedback and reviews

1-3 stars or Feedback open feedback with stars and interface language. Removal opens the optional goodbye survey at /bye with extension version (v) and language (l) through Cloudflare Pages. Submissions include reason, comment, version and language; comments reach the publisher through Telegram. Uncommented submissions are stored only as counts. 4-5 stars open Chrome Web Store reviews once configured.

Retention and deletion

Recent rows remain until deleted, displaced by the 20-row limit or uninstalled; New starts another diagram without deleting saved rows. Uninstall clears preferences and rating state, not exported files, clipboard copies or records held by external services.

Your rights

Where applicable, you can learn how data is used, access, correct or delete it, restrict or object to processing, request portability, withdraw consent, complain to a supervisory authority and exercise California rights without discrimination.

Children

Sequence Diagram is intended for users 13 and older.

Limited Use

Sale and unrelated use or sharing of user data are prohibited.

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
