Cookies are small text files stored on your device by your browser when you visit a website. They serve various purposes | from keeping you logged in to tracking you across the web for advertising. Stelo uses only the former.
In addition to traditional cookies, modern web apps also use browser storage mechanisms such as LocalStorage and SessionStorage. These work similarly to cookies but are stored locally on your device and are not automatically sent to servers with each request.
Stelo sets no cookies at all. That is not a turn of phrase: the app never writes to document.cookie, and your session is held in your browser's LocalStorage instead. The table below lists every piece of information Stelo stores on your device, all of it strictly necessary to keep you signed in and the app usable offline. None of it is used for advertising, profiling or cross-site tracking.
| Name | Purpose | Type | Expiry |
|---|---|---|---|
sb-dwszyeqgisbeiaxhcnxm-auth-token |
Your signed-in session, issued by Supabase Auth. Stored in LocalStorage, not as a cookie, so it is never attached automatically to outgoing requests. | Until you sign out | |
stelo-auth, habitus_v1 |
Your account state and a local copy of your habits, check-ins and todos, so the app opens instantly and keeps working offline. | Until you sign out or clear site data | |
stelo_calendar, stelo_pomodoro, stelo-challenges |
Your calendar view, pomodoro timer state and challenge progress, kept locally so a reload does not lose a running session. | Until you clear site data | |
stelo_sidebar_collapsed, stelo_review_state_v1 |
Interface preferences: whether the sidebar is collapsed, and whether we have already asked you to rate the app, so we do not ask twice. | Until you clear site data |
In addition to cookies, the Stelo web app uses LocalStorage to store preferences and cached data on your device. This data never leaves your browser unless you are syncing it to your account.
LocalStorage is used for:
LocalStorage data can be cleared at any time by clearing your browser's site data for steloapp.io or app.steloapp.io.
To be explicit about what we do not do:
There is no consent banner because there is nothing to consent to: Stelo stores no cookies, and the LocalStorage entries above are all strictly necessary to deliver a service you asked for. Under the ePrivacy rules, storage that is strictly necessary for a service the user requested does not require prior consent. You cannot opt out of it and keep a working signed-in session, in the same way you cannot opt out of the app remembering who you are.
If we ever add storage that is not strictly necessary, such as product analytics, we will ask for your consent before setting it, and this page will say so before it happens.
You can delete cookies at any time through your browser settings:
Note that clearing cookies will log you out of Stelo. Your data is safely stored in your account and will be available when you log back in.
We may update this Cookie Policy if we change the cookies or storage mechanisms we use. We will update the "Last updated" date at the top of this page and, for material changes, notify you via an in-app notice.
