This page explains what STCKD stores on your devices, on our website stckd.app and in the app, and why. It adds to our Privacy Policy.

1. Summary

2. Our website

stckd.app sets no cookies and uses no local storage, session storage or other browser storage. It loads no analytics, advertising, tracking pixels, embedded videos or outside fonts. Everything comes from stckd.app itself.

Password-reset page. When you open a password-reset link from our email, this page connects to our sign-in provider, Supabase, to set your new password. The reset session is kept only in the page's memory. Nothing is saved in your browser, and the session is gone when you close the page.

Our website host, GitHub Pages, logs visitors' IP addresses for security. It does not use cookies for this.

About __cf_bm. Our database provider, Supabase, uses Cloudflare to protect its network. Cloudflare may send this bot-protection cookie with its answers when the app talks to our servers. It is not used to track you, and we cannot read it.

Data stored in the app is not sent to us unless you have an account and have given your health-data consent (see the Privacy Policy). Your iPhone backups (iCloud or computer) may include the app's storage.

4. Why there is no consent banner

The law (Slovak Act No. 452/2021 Coll. on Electronic Communications, §109(8), based on the EU ePrivacy Directive) requires consent before a website or app stores or reads information on your device. There is an exception for storage that is strictly necessary to provide a service you explicitly asked for. Everything above falls under that exception. If we ever add anything that is not strictly necessary, such as analytics, we will ask for your consent first and update this page.
