Cookie Policy
Last updated: 2026-04-29
This page describes the cookies and similar local-storage technologies used by BookSlash and what you can do to control them. It supplements our Privacy Policy.
1. What is a cookie?
A cookie is a small text file stored by your browser. We also use related browser storage APIs (localStorage, sessionStorage, IndexedDB) for the same purposes. For brevity we refer to all of these as “cookies”.
2. Categories of cookies we use
Strictly necessary
These cookies are required to deliver the service and cannot be turned off. They include session tokens, CSRF tokens, and load-balancer routing cookies.
Functional
These remember UI preferences (theme, last opened workspace, sidebar state). They are first-party only and are not used to track you across sites.
Analytics
We use first-party, privacy-respecting product analytics to count active workspaces and understand which features are used. We do not use third-party advertising trackers.
Third-party
Paddle sets cookies on the checkout and billing pages it hosts to prevent fraud and comply with tax regulations. Those cookies are governed by Paddle’s privacy notice.
3. The cookies we set
| Name | Category | Purpose | Lifetime |
|---|---|---|---|
| better-auth.session_token | Strictly necessary | Session authentication. | 30 days |
| better-auth.csrf_token | Strictly necessary | CSRF protection on form submissions. | Session |
| bookslash.workspace | Functional | Remembers the last active workspace. | 1 year |
| bookslash.theme | Functional | Remembers your theme preference. | 1 year |
4. How to control cookies
- Browser settings let you block or delete cookies. If you block strictly necessary cookies, the service will not work.
- We honor the Global Privacy Control (GPC) signal as a do-not-sell / do-not-share request where applicable.
- To exercise data subject rights described in our Privacy Policy, email [email protected].
5. Changes
If we add or change cookies in a material way, we will update this page and the “Last updated” date.
