Privacy Policy

Last updated: 28 September 2026

Who we are

Chart runs Chart. This policy explains what personal data the service keeps, why, and your rights. Contact us through the contact details on the website.

What we keep

Why

To provide the service you signed up for (the contract with you), to keep it secure (our legitimate interest), to handle payments and keep accounting records (legal obligation), and to send the emails the service needs: confirming your email, password resets, receipts, and reminders before your trial or Pro ends. We don’t send marketing email and we don’t sell your data.

Who else processes it

Cookies

We use a login cookie that keeps you logged in, and a referral cookie (30 days) when you arrive through a friend’s link. Your browser also stores your chart settings locally so the app opens fast. There are no advertising or tracking cookies.

How long

Your data is kept while your account exists. When you delete your account, your content is deleted at once; payment records are kept as long as accounting law requires. Security records are kept for at most a few days.

Your rights

You can see and download your data (Account & billing, and “Download my data”), correct it, and delete your account at any time. Depending on where you live (for example under the GDPR) you may also object to or restrict processing and complain to your data protection authority. Contact us for anything you can’t do in the app.

Security

Passwords are hashed, data files cannot be downloaded from the web, connections use HTTPS, and each account’s data is kept apart from the others’. No system is perfectly secure; please use a strong, unique password.

Changes

We will post changes to this policy here and, if they are significant, tell you by email.
