Cookie Policy
Last updated 25 September 2026
Cinderra does not have a cookie banner, because it does not have the kind of cookies that need one. There is no advertising network here, no analytics vendor, and nothing following you to other websites. This page lists everything the site stores in your browser.
01What is stored
| Name | Kind | What it does | How long it lasts |
|---|---|---|---|
| sb-*-auth-token | Cookie — strictly necessary | Sign-in session. Keeps you signed in. Set by our authentication provider and split across a few cookies when the session is large. | Until you sign out, or one year |
| sb-*-auth-token-code-verifier | Cookie — strictly necessary | A one-time value that completes a sign-in securely. | Minutes, then discarded |
| theme | Local storage | Theme. Whether you chose the light or dark theme. | Until you clear it |
| cinderra:appearance | Local storage | Appearance. Accent colour, density, corners, canvas pattern, text size and motion. | Until you clear it |
| cf:appearance | Local storage | Appearance (old name). The same preferences under the name they had before a rename. Moved and removed on your next visit. | Until your next visit |
| cinderra:recent-board-icons | Local storage | Recent board icons. The last few emoji you picked as board icons, so the picker can offer them again. | Until you clear it |
| cinderra:notifications | Local storage | Desktop alerts. Whether you switched desktop alerts on or off in Settings. | Until you clear it |
| cinderra:minimap | Local storage | Minimap. Whether the minimap is open, and where. | Until you clear it |
| cinderra.sidebar.collapsedBoards | Local storage | Folded boards in the sidebar. Which nested boards you folded away. | Until you clear it |
| cinderra.sidebar.boardOrder | Local storage | Sidebar order (copy). A copy of your sidebar order, so it shows before your account has loaded. | Until you clear it |
| cinderra-note-viewer-size | Local storage | Note viewer size. Whether you open notes large, filling the window, or in a smaller viewer. | Until you clear it |
| cinderra-log-hour-height | Local storage | Log board zoom. How tall an hour is drawn on log boards. | Until you clear it |
| cinderra-draft:<board> | Local storage | Unsaved changes. Edits made while you were offline, one entry per board, held until they reach the server. Clearing one loses those edits. | Until saved, or seven days |
| cinderra:signup-source | Local storage | Signup answer in transit. Your “how did you hear about us?” answer, held while you finish signing up with Google. | Until signup finishes, or one day |
| cinderra:demo-board | Local storage | Demo board. A board you made on the demo before signing up, so it can become your first real one. | Until you sign up, or one day |
| cinderra:landed | Session storage | Landing redirect. Notes that you have already been sent to your boards once, so “All boards” does not bounce you back. | Until you close the tab |
| cinderra:last-board | Session storage | Last board. The board you had open, so the app can take you back to it in this tab. | Until you close the tab |
| cinderra-tutorial-step | Session storage | Tutorial progress. Which step of the tutorial you are on. | Until you close the tab |
| cinderra-hints-dismissed | Session storage | Dismissed hints. That you closed the canvas hints. | Until you close the tab |
| cinderra-jump-trail | Session storage | Card link trail. The cards you jumped between with card links, for the back button. | Until you close the tab |
| cinderra-pending-focus | Session storage | Card to focus. The card a link is about to open, while the board loads. | Until you close the tab |
That is the complete list. If you find something else, it is either a bug or something a browser extension of yours put there.
Settings → Privacy shows which of these this browser is holding right now, and clears any of them.
02Why there is no banner
The ePrivacy rules require consent for storage that is not strictly necessary for a service the user has asked for. Sign-in cookies are necessary by definition — without them you would be signed out on every page load — and every other entry above holds a preference you set yourself, on your own device, which never leaves it.
A few entries exist so you do not lose work or get asked twice — unsaved offline edits, a demo board carried into your first real one, a signup answer held across a Google sign-in. They expire on their own and are cleared the moment their job is done.
Nothing here is used to identify you across sites or build an advertising profile, so there is nothing to ask permission for. If we ever add analytics, this page will change and a real consent prompt will appear before anything is set.
03Third-party cookies
We do not set any. Two things are worth knowing about anyway:
- If you sign in with Google, Google sets its own cookies during that exchange, on its own domain, under its own privacy policy. We have no control over them and no access to them.
- If you subscribe, PayPal does the same on its checkout pages.
04The browser extension
The extension does not use cookies. It keeps your session and your chosen board in the browser’s own extension storage, which no website can read. Signing out of the extension deletes both, and so does the “Clear local data” button on its options page.
05Clearing them
Every browser lets you delete cookies and site data, usually under Privacy or History. Removing ours signs you out and resets your interface preferences to their defaults; nothing on your boards is affected, because none of it lives in your browser.
Questions about anything on this page: admin@northem.no.
In short
Sign-in cookies, and preferences and work-in-progress saved on your own device. That is the entire list, which is why there is no banner asking you to accept anything.
- Sign-inTwo cookies keep you logged in. Strictly necessary — without them you would be signed out on every page load.
- PreferencesYour theme, appearance and layout settings, and a few short-lived notes such as unsaved offline edits. All stored locally, none of it sent to us.
- TrackingNone. No analytics, no advertising, no session recording, nothing following you to other sites.
- Other companiesWe set no third-party cookies. Google sets its own if you use Google sign-in, and PayPal does the same at checkout — on their domains, under their policies.
- Clearing themSettings → Privacy, one entry at a time, or your browser’s privacy settings. Your boards are not affected, because none of them is stored in the browser.
This summary is here to be read, not relied on. It is not part of the Cookie Policy and it does not change a word of what is above it — where the two disagree, the document wins.
