Privacy Policy
Chalk ("we", "us") is a workout tracking app. This policy explains what information the Chalk app and website collect, how we use it, and the choices you have. The short version: we collect only what is needed to run your account and store your training, we do not track you, and we never sell your data.
Information we collect
Information you provide
- Account information: your email address and a password. Your password is stored only as a salted hash; we cannot read it.
- Training data: the workout templates, exercise names, sessions, sets, weights, repetitions, target percentages, and max-effort records you enter in the app.
Information stored on your device
- A sign-in token, kept in your device's secure storage (the iOS Keychain), so you stay signed in. It is removed when you sign out.
Information we do not collect
Chalk does not collect your location, contacts, photos, health or fitness data from Apple Health, advertising identifiers, or device identifiers. Chalk contains no third-party analytics, advertising, or tracking software, and does not track you across other companies' apps or websites.
How we use your information
- To create and secure your account and sign you in.
- To store your workouts and history and sync them to your account, so they are available if you switch phones.
- To provide app features, such as calculating working weights from your target %1RM.
- To respond to support and privacy requests you send us.
We do not use your data for advertising, and we do not sell or share it with data brokers.
How we share information
We do not sell your personal information. We share it only with service providers that host our servers and database and act on our behalf under appropriate confidentiality and security obligations. We may also disclose information if required by law or to protect the rights, safety, and security of our users or Chalk.
Data storage and security
Your data is stored on servers operated by third-party cloud hosting providers, which may be located in the United States. Data is transmitted over encrypted (HTTPS) connections, and passwords are hashed. No method of transmission or storage is completely secure, but we work to protect your information.
Data retention and deletion
We keep your data for as long as your account exists. You can delete individual workouts and max-effort records in the app at any time. To delete your account and all associated data, email tjvonbr@gmail.com from the address on your account. We will permanently delete your account and training data within 30 days, except where we must retain information to comply with legal obligations.
Your rights and choices
Depending on where you live (for example, the EEA, UK, or California), you may have the right to access, correct, export, or delete your personal information, and to object to or restrict certain processing. To exercise any of these rights, contact us at the email below. We do not discriminate against you for exercising your rights.
Children's privacy
Chalk is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has given us personal information, contact us and we will delete it.
Changes to this policy
We may update this policy from time to time. When we do, we will change the effective date above, and for material changes we will notify you in the app or by email.
