Your knowledge stays on your device
Eigma runs in your browser. Your wiki, quizzes and memory state live in your browser's local storage on your device. Using Eigma without an account sends none of your knowledge to us.
Signing in and Google user data
Signing in (email link, Google or GitHub) creates an account. When you sign in with Google, we receive your email address, name and basic profile information (such as your avatar) from your Google Account. We use this only to create and identify your Eigma account and to provide an automatic cloud backup of your wiki. This data is stored with our infrastructure provider (Supabase) and is readable only by your account. We do not sell it, use it for advertising, or share it with third parties. Eigma's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Deleting your data
You can delete your account and all associated cloud data at any time from the account settings in the app, or by emailing us at eigma.app@gmail.com. Deletion removes your backup from our infrastructure.
What we do not do
No ads, no selling data, no third-party tracking pixels on this site or in the app.
This policy will grow
Eigma is young. As features like Pro arrive, this page will describe exactly what changes, in plain language.
