This Cookie Policy explains what cookies and similar technologies are, how StoryLegend uses them on the Family Tree Builder, and how you can manage your preferences.
Cookies are small text files placed on your device by a website. They are widely used to make websites work, improve efficiency, and provide information to site operators. We also use browser localStorage — a similar technology that stores data on your device without an expiry date — for features like saving your trees when you are not signed in.
We use three categories of cookies and similar storage technologies:
Essential for the Service to function. Cannot be disabled.
| Name | Purpose |
|---|---|
| supabase-auth-token | Keeps you signed in across sessions |
| cookie_consent | Remembers your cookie preference |
| tree-data (localStorage) | Stores tree data locally for no-account usage |
| theme (localStorage) | Remembers your light/dark mode preference |
Help us understand how the Service is used. Only loaded after you accept.
| Name | Purpose |
|---|---|
| _ga, _gid | Google Analytics — distinguishes users and sessions |
| _gtm_* | Google Tag Manager — manages analytics script loading |
Used for marketing attribution, campaign measurement, and related promotional activity. Only loaded after you enable them.
| Name | Purpose |
|---|---|
| _gcl_* | Google advertising and conversion measurement cookies when ad features are active |
| _fbp or similar | Advertising or remarketing cookies from marketing platforms if used in future campaigns |
You have full control over analytics and marketing cookies:
Rejecting optional cookies does not affect your ability to use the Service. All core features remain fully available.
When you accept analytics cookies, Google Analytics sets cookies on your device via Google Tag Manager. These are governed by Google's Privacy Policy. If you enable marketing cookies, advertising or campaign-measurement providers may also set cookies through Google Tag Manager or similar tools when those integrations are active. Any such providers will be governed by their own privacy policies.
We may update this Cookie Policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the Service after changes are posted constitutes your acceptance of the revised policy.
