1. What we use
Stashiro uses cookies, local storage, and similar browser technologies to keep users signed in, protect sessions, remember interface choices, store guest boards locally, support billing and checkout, and keep the service secure. Browser storage is also used to cache board data, remember selected boards, support the browser extension handoff, and preserve local demo content.
2. Strictly necessary storage
Necessary cookies and storage are required for core functionality such as authentication, security, paid access, sidebar preferences, guest boards, cloud board caching, billing, and extension-to-web handoff. These are not optional because the product cannot work properly without them.
- Better Auth cookies keep signed-in sessions working.
- Convex and app state identify the account, cloud boards, shared board access, and subscription entitlement.
- Local storage keeps guest boards, cached board data, local transfer state, sidebar preferences, quick-add choices, the extension's account-scoped board cache, and its last selected board.
- The extension uses browser session storage for short-lived authentication tokens rather than persistent local storage.
- A sidebar preference cookie remembers whether the in-app sidebar is open.
- Stripe Checkout and the Stripe customer portal may use cookies or similar technologies needed for subscription checkout, billing details, invoices, payment methods, fraud prevention, and subscription management.
3. Optional cookies
Stashiro may load optional analytics and diagnostics storage when Sentry or PostHog is configured. Sentry helps diagnose errors, crashes, traces, and regressions. PostHog helps understand page views, feature interactions, session analytics, and product usage.
Optional analytics, advertising, or marketing tools should not run until Stashiro asks for any consent required by law, and this page should include real controls to accept, reject, or withdraw those choices when those controls are required.
4. Third-party cookies
Authentication, payment, embedded previews, maps, media players, and websites opened from saved links may use their own cookies or similar technologies under their own policies. Browser settings can usually block or delete cookies, but doing so may break sign-in, checkout, or saved preferences.
Boards can display third-party content such as social posts, videos, map tiles, product previews, travel previews, and shopping previews. Those providers may receive requests from your browser when the content is loaded or interacted with. Stashiro does not control those providers' cookies.
6. Managing browser storage
You can clear local browser data or use browser privacy controls to delete cookies and local storage. Clearing local storage may delete guest boards that were never transferred to cloud storage.
