Privacy Policy

Last updated: 2026-08-05

This Privacy Policy describes how PlanChart ("we", "us", "our") collects, uses, and shares information when you use planchart.ai (the "Service").

We aim to collect the minimum information needed to operate the Service. We do not sell personal data.

Information We Collect

We collect and process the following information:

Device identifier (hashed). A rotating SHA-256 hash of your IP address and browser user-agent, used to prevent abuse of rate limits and as an anonymized session identifier. We do not store raw IP addresses.
Interaction events. Clicks, page views, feature use — used to understand which features are used. Events are associated with your hashed device identifier, not you personally.
Automatically collected. Standard web-server logs (timestamp, path, response code, user-agent, referrer).

We do not collect: your name, phone number, physical address, date of birth, or payment card information (payments, if any, are handled by third parties — see below).

How We Use Information

To rate-limit and detect abuse.
To improve the product (aggregate analytics about feature usage).

Donations

Optional tips and donations are processed by Buy Me a Coffee. We receive no payment card information. Refer to their privacy policy.

Cookies

We use the following categories of cookies and similar storage:

Functional — session tokens and browser storage to keep you logged in and remember your preferences. You can clear these at any time via your browser.

We honor the Do Not Track (DNT) browser signal — if your browser sends DNT, we do not track interaction events.

Data Sharing

We share data with the following third parties strictly as necessary to operate the Service:

Fly.io — our hosting provider (privacy policy).

We do not sell or rent personal information to any third party.

Data Retention

Interaction events are kept for operational analysis and may be aggregated indefinitely. We do not retain raw IP addresses.

Your Rights

Because we do not collect personally identifying information, there is no personal account to access or delete. You may also:

Clear your browser storage to remove device-side state.
Use DNT in your browser settings to avoid interaction tracking.
Contact us at hello@planchart.ai with any requests.

Children

This Service is not directed at children under the age of 13, and we do not knowingly collect personal information from children. If you believe a child has submitted information, please contact us.

Changes to This Policy

We may update this policy. When we do, we'll update the "Last updated" date at the top. Material changes will be noted on the site.
