Cookie notice
Template notice: this page is a plain-language template. A qualified lawyer should review it before public launch.
Here's everything DearFutureMe stores in your browser and why. Most of it uses your browser's local storage rather than cookies, but we list it all here the same way.
| What | Where | Why | How long |
|---|---|---|---|
| Sign-in session | Browser local storage (sb-… keys) | Keeps you signed in after you use a sign-in link. | Until you sign out, or about a week of inactivity. |
| Draft letter | Browser local storage (dfm-draft…) | Keeps your draft safe if you close the tab. Only on your own device, never on booth devices. | Until you send the letter or clear it. |
| Theme | Browser local storage (dfm-theme) | Remembers light or night-writing mode. | Until you clear site data. |
| Booth device registration | Browser local storage, booth devices only | Proves the device was set up by event staff. Contains no attendee data. | Until staff remove or revoke it. |
| Bot check | Cloudflare Turnstile | Tells people from bots on forms. May set a strictly necessary security cookie. | Short-lived, set by Cloudflare. |
Analytics
If we ever measure visits, we'll only use a cookieless, privacy-friendly tool such as Cloudflare Web Analytics, and we'll update this page and the Privacy Policy first.
Clearing it
You can clear all of this through your browser's “clear site data” setting. If you do, you'll be signed out and any unsaved draft on that device will be lost.
