This policy covers browser storage used on devtune.ai, the DevTune app and docs.devtune.ai. Read it with our Privacy Policy.
If you are in the United Kingdom, European Economic Area or Switzerland, we ask before analytics runs. Essential storage and support chat remain available because the service needs them to work.
Everywhere else, analytics is on by default and you can switch it off at any time.
We keep your decision for 12 months, then ask again. Analytics stays off in consent-required regions until you answer.
If your browser sends Global Privacy Control, we treat it as a rejection everywhere. We do not act on the older Do Not Track setting.
Keeps your sign-in session and security tokens, language and theme, consent choice, and app preferences such as the project you last opened. Set by DevTune and Supabase; kept from the current session up to 400 days depending on the item. No consent is needed.
Measures site and app usage with PostHog in the EU, Google Analytics on the marketing site, and DevTune's own AI-traffic measurement. It stays off until you accept where consent is required; data lasts up to 2 years for Google Analytics, 1 year for PostHog, and the current tab for our measurement.
On devtune.ai marketing pages, Cossistant chat loads only when you open it and stores nothing before that. It keeps your conversation available across pages and knows who you are when you are signed in. Local storage remains until cleared, and session data remains until the current tab closes. This is functional storage and does not need consent.
| Category | Purpose | Duration | Needs consent |
|---|---|---|---|
| Essential | Sign-in, security, consent and app preferences | Session to 400 days | No |
| Analytics | Site, app and AI-traffic measurement | Current tab to 2 years | Yes, where required |
| Support chat | Keep support conversations across pages, only after you open chat on the marketing site | Current tab or until cleared | No |
When a page errors, and on a sample of page loads for performance monitoring, the browser sends a report to Sentry in the EU with the page URL, browser details and your IP address. Sentry sets no cookies. We rely on our legitimate interest in keeping the service working.
Use the Cookie manager here or in the footer. Turning analytics off expires Google Analytics cookies, opts PostHog out, and stops DevTune's own AI-traffic measurement.
We update this page when what we store changes. The date at the top shows the current version.
