Loadmate – Privacy Policy
Last updated: 16 October 2026
Loadmate ("the extension") is a Chrome extension that shows chess puzzles while an AI chatbot is writing its answer. This policy explains what data the extension handles, why, and your rights.
Who is responsible
The data controller is Enrico Zafiris, 38518 Gifhorn, Germany. Contact: enricozafcode@gmail.com
What Loadmate does not do
- It does not read, store or send the content of your AI conversations. On ChatGPT, Claude, Gemini and Perplexity it only checks whether the site's "Stop" button is visible, to know when the AI is writing.
- It does not track the websites you visit, show ads, or sell or share your data.
What data is stored
| Data | Why | Where |
|---|---|---|
| Your settings (board theme, sound, panel size and position, which sites are enabled) | To remember your preferences | Your browser (Chrome sync storage) |
| Puzzle results: which puzzle, solved or not, when, and your rating before/after | To match puzzles to your level and show your progress | Your browser and our database |
| A random account ID (created automatically, no personal details) | To keep your progress when you use Loadmate as a guest | Our database |
| Your email address and name — only if you choose "Sign in with Google" | To identify your account so your progress is available on all your computers | Our database (provided by Google) |
Legal basis (GDPR): performance of the service you requested (Art. 6(1)(b)) — storing your results is what makes the rating and progress features work. Signing in with Google is optional.
Service providers
- Supabase (database and sign-in). Our data is stored in Supabase's London, United Kingdom region. The United Kingdom is recognised by the European Commission as providing an adequate level of data protection. Supabase, Inc. processes data on our behalf under a data processing agreement that includes the EU Standard Contractual Clauses.
- Google — only if you choose "Sign in with Google": Google confirms your identity and shares your name and email address with us. Google's own privacy policy applies to your Google account.
How long data is kept
Your data is kept until you delete it. You can delete everything at any time (see below). Uninstalling the extension removes the data in your browser; to also remove the data in our database, use "Delete my data & account" first, or contact us.
Your rights
You have the right to access, correct, export and delete your data, to restrict or object to processing, and to complain to a data protection authority.
- Delete your data: directly in the extension (toolbar icon → Your data & privacy → Delete my data & account). This permanently deletes your account, rating, puzzle history and settings from our database and your browser, and removes the link to your Google account.
- Get a copy of your data or exercise any other right: email enricozafcode@gmail.com. We respond within one month.
Children
Loadmate is not directed at children under 16, and we do not knowingly collect their personal data.
Changes
If this policy changes, the new version is published on this page with a new date.
