Cookie Policy
How we use cookies and similar technologies.
Last updated: 14 March 2026
What cookies are
Cookies are small text files a website stores on your device to remember things like your login and preferences.
Cookies are small text files stored on your device when you visit a website. They help a site remember things like whether you are logged in and what settings you prefer.
Similar technologies we may use:
- Local storage: browser storage for app data, kept longer than a cookie.
- Session storage: temporary storage that clears when you close your browser.
We do not use tracking pixels.
Cookies we use
Two kinds: essential cookies that keep Owdyn working, and functional cookies that remember your preferences.
These keep Owdyn working and are required.
| Cookie | Purpose | Duration |
|---|---|---|
| __Secure-next-auth.session-token | Keeps you logged in (cleared when your browser closes) | Session |
| __Secure-next-auth.csrf-token | Prevents cross-site request forgery attacks | Session |
| __Secure-next-auth.callback-url | Redirects you after sign-in | Session |
These remember your preferences and can be cleared without affecting sign-in.
| Cookie | Purpose | Duration |
|---|---|---|
| theme-preference | Remembers light or dark theme | 1 year |
| owdyn_trusted_device | Remembers trusted devices to reduce 2FA prompts | 30 days |
Cookies we do not use
No advertising, no cross-site tracking, no social media cookies, no profiling analytics.
We do not show ads or track you for advertising. No Google Ads, no Facebook Pixel.
We do not follow you across other websites. Your Owdyn activity stays in Owdyn.
No Facebook, Twitter, or LinkedIn widgets, and no social tracking.
No Google Analytics or similar that builds a profile of you. We use basic server logs only.
Third-party cookies
All Owdyn cookies are first-party. There are two narrow exceptions.
Cookies set by Owdyn come only from the owdyn.com domain. We do not use third-party cookies for tracking or advertising. Two exceptions:
- Google sign-in: if you sign in with Google, Google may set its own cookies to manage that sign-in. We do not control or use those for tracking.
- Canny (public roadmap): when you submit in-app feedback, Owdyn calls Canny from our server, so no Canny cookies are set on owdyn.com. If you visit our public roadmap at owdyn.canny.io directly, Canny may set its own cookies there, governed by Canny's privacy policy.
Controlling cookies
You can manage cookies in your browser, and some preferences directly in Owdyn.
Browser settings
Most browsers let you control cookies:
- Chrome: Settings → Privacy and security → Cookies and other site data.
- Firefox: Settings → Privacy and Security → Cookies and Site Data.
- Safari: Settings → Privacy → Manage Website Data.
- Edge: Settings → Cookies and site permissions → Cookies and site data.
Blocking essential cookies will stop you signing in to Owdyn. Functional cookies are optional and can be cleared without affecting access.
In Owdyn
- Change your theme in Settings → Preferences.
- Manage 2FA trusted devices in Settings → Security.
- Clear all preferences by signing out and clearing your browser data.
How long cookies last
Session cookies clear when you close your browser. Persistent cookies stay for a set time until you delete them.
Session cookies
Clear when you close your browser. We use them for:
- Sign-in (the authentication token lasts up to 24 hours while your browser is open)
- CSRF protection
- Post-sign-in navigation
Persistent cookies
Stay for a set period, or until you delete them. We use them for:
- Theme preference
- Trusted devices
Durations are in the cookies table above. You can delete these anytime in your browser.
Updates to this policy
If we make significant changes, we will let you know.
We may update this policy from time to time. If we make significant changes, such as adding a new type of cookie, we will tell you by email, by an in-app notice, or by updating the date at the top of this page. We suggest reviewing it from time to time.
