Cookie Policy

This Cookie Policy explains how Keisan uses cookies and similar browser storage. It is short on purpose: Keisan uses essential storage for sign-in, security, preferences and running the product, and PostHog storage for product analytics. We do not use advertising cookies.

Cookies are small text files stored by your browser. Similar technologies, such as local storage, can remember settings or temporary state so the Service works between page loads.

Keisan may use the following kinds:

• Sign-in: keeps you signed in and protects access to your account.
• Demo: when you choose Try the demo, two cookies open the demo workspace and show the demo banner. They last seven days or until you sign out.
• Security: helps prevent abuse and keeps sessions intact.
• Preferences: may remember interface choices between visits.
• Billing: Stripe sets cookies during checkout to process payments securely.
• Analytics: PostHog cookies and local storage, with names that start with ph_, used for product analytics. They are set on .jishulabs.com, so they are shared with jishulabs.com and the other Jishu Labs tools, and last up to one year. If you declined cookies on jishulabs.com, analytics is not loaded.

• No third-party advertising cookies
• No behavioral ad targeting
• No sale of cookie-derived data
• No use of your briefs or estimates for advertising profiles

You can block or clear cookies in your browser settings. Blocking essential cookies may stop sign-in, account security, billing or parts of the product from working.
