Privacy — Last updated: 7 November 2026

• Who is responsible: TeamSync is made by Simeon Tsvetanov, Bulgaria (contact: email (needs JavaScript)). The names you type stay on your device and under your control only.
• In the browser: the names you type are split into teams entirely on your device. They are not uploaded anywhere. Names are never put in TeamSync links (only the number of teams, e.g. ?teams=3). Please only enter names of people who are fine with it — they stay on this device.
• Sharing: when you tap Share, WhatsApp or Copy, the teams text goes to the app you choose and is then covered by that app's own privacy terms. On Android, a list you share into TeamSync arrives in the address and is removed from it right away.
• Stored on your device only: your settings (theme, language, number of teams), your last names list (so it is still there next time), which tips and prompts you already dismissed, and an unsent problem report draft (its text) are kept in your browser's own storage on this device (local storage). They never leave your device and are not synced anywhere. TeamSync does not save anything in IndexedDB or the browser's private file storage (OPFS); Settings → Storage only looks there when you export or clear your data. You can see the space used, export, or delete your data in Settings → Storage, or by clearing this site's data in your browser.
• Offline copy: so TeamSync works without internet, your browser keeps an offline copy of the app's own files (not your names) in its Cache Storage, managed by a service worker. If you tap Keep data on this device in Settings → Storage, the app asks the browser to keep this site's storage persistent (navigator.storage.persist()), so it is not cleared automatically when space runs low. Clearing this site's data removes both.
• No accounts, no ads, no tracking, no cookies, no analytics.
• Local AI-agent tool (MCP): if you run npx -y @simeonts/teamsync-random-team-generator-mcp, it runs on your own computer; the names your agent sends to it are not sent to us.
• Problem reports: if you send a report, its text and the diagnostics you leave ticked are posted as a public GitHub issue through GitHub (you need a free GitHub account); GitHub's privacy statement applies. TeamSync does not ask for or send your email.
• Hosting: the site is hosted on GitHub Pages. GitHub logs visitor IP addresses for security purposes — see the GitHub Privacy Statement.
• Email to the contact address: if you write to email (needs JavaScript), your message and address are used only to answer you, are not shared with anyone, and are deleted at the latest one month after the conversation ends.
