Last updated: 2 October 2026
1. What Cookies Are
Cookies are small files placed on your device. Similar technologies include local storage, session storage and software development kit storage used by browsers or apps.
2. Essential Cookies and Storage
LetLog uses essential cookies and browser storage to provide login, security and core app functionality. These are necessary for the service and cannot be switched off in LetLog.
| Name or pattern | Purpose | Typical duration |
|---|---|---|
| sb-* | Supabase authentication and session management | Session or refresh-token lifetime |
| __letlog_csrf | Protection against cross-site request forgery | Temporary security token |
| letlog-bootstrap | Short-lived app profile cache to reduce page-load requests | About 5 minutes |
| localStorage entries | Theme, sidebar, profile and app state preferences | Until changed, expired or cleared |
| letlog-analytics-consent (local storage) | Remember your analytics cookie choice | 180 days, or until changed or cleared |
3. Payments and Third-Party Services
When you use billing or checkout features, Stripe may set cookies or similar technologies to process payments, prevent fraud and keep checkout secure. Third-party providers may also process technical data needed to provide hosting, authentication, storage, email, push notifications, error monitoring and security.
4. Analytics and Marketing Cookies
If you allow analytics, we use Microsoft Clarity on public marketing and legal pages to understand visits, clicks and scrolling, create heatmaps and review masked session recordings. Clarity does not load before you allow analytics, and we keep it off sign-in, invitation and private application screens.
Clarity may set the first-party cookies _clck (a visitor identifier and preferences) and _clsk (joining page views into a session). Microsoft documents its cookies and their purposes in the Clarity cookie documentation. We do not enable advertising storage through this integration. For Microsoft's handling of analytics data, see the Microsoft Privacy Statement.
5. Managing Cookies
Use Cookie settings in the public website footer to allow or refuse analytics at any time. Choosing Essential only stops Clarity and clears its LetLog cookies. We remember your choice for 180 days before asking again. Withdrawing consent stops future collection but does not automatically erase data already collected.
You can block or delete cookies through your browser settings. Blocking essential cookies may stop login, security or app features from working correctly.
