GanttCalc is run by Kacharuk [legal name], [city], Thailand. We collect as little as we can.

• Demo. What you type into the demo stays in your browser. We don't receive it, unless you turn on AutoSave.
• Demo AutoSave (cloud). If you turn on AutoSave, your plan and its recent versions are stored with Cloudflare, our hosting provider, under a secret link. There is no account: anyone with the edit link can open and change the plan, and anyone with a view-only link (only if you create one) can see it. You can reset the links or delete the plan from the AutoSave menu at any time. Plans are deleted 30 days after the last change. To stop bots, Cloudflare Turnstile checks your browser when you turn AutoSave on, and we count saves per device (a scrambled form of your IP address, kept one day) to limit abuse. We keep no other record of who saved what.
• Usage analytics. We count page views and a few actions, such as "edited a formula", using PostHog on its EU servers. It doesn't use cookies or identify you.
• Email signup. If you give us your email, we use it to send the launch email and a few updates for founding members (about one a week until launch). It is stored with Cloudflare, our hosting provider. Every email has an unsubscribe link.
• Payments. Lemon Squeezy processes payments as merchant of record. We receive your name, email, country and order details, never your card number. See Lemon Squeezy's privacy policy.
• We never sell your data or share it with advertisers.
• Your rights. You can ask to see, correct or delete your data at any time by emailing [email protected]. If you are in the EU or UK, you also have the right to complain to your local data protection authority.
• Retention. We delete signup emails 12 months after launch if you never became a customer, and keep order records as long as tax law requires.
