Privacy Policy

Last updated 12 August 2026

What Gridlines collects, why we collect it, who else sees it, and what you can ask us to do with it. Training data is personal; this page is meant to be readable rather than exhaustive.

1. Who this covers

This policy explains how Unit Fitness Solutions, Inc. handles personal data across Gridlines — the website, the builder, and the mobile app. It covers coaches, organization staff, and athletes alike; where a difference matters, it is called out.

2. What we collect

Account data. Your email address, name, and authentication details. If you sign in with Google, we receive your email and basic profile from Google — not your Google password.

Organization and roster data. Organization names and settings, team membership, staff roles, and invitations.

Training content and results. Programs, exercises, protocols, and the sessions athletes complete — sets, reps, loads, times, and notes. For athletes this is the substance of the service.

Communications. Direct messages and community posts, including reports made about them.

Storefront and commerce data. Public seller profile fields, listings, purchases, subscriptions, and payout status. We do not receive or store your full card number. Card details go directly to Stripe; we see only what Stripe returns, such as the card brand and last four digits.

Technical data. IP address, device and browser information, and logs of requests to the service, kept for security and debugging.

3. Why we use it

  • To run the service — showing an athlete their session, showing a coach the work that came back, delivering a purchased program.
  • To authenticate you and keep accounts secure.
  • To take payments, pay sellers out, and meet our tax and accounting obligations.
  • To send service messages: invitations, receipts, security notices, and — if you opt in — push notifications.
  • To support you when you ask for help.
  • To investigate abuse and enforce our terms and community guidelines.

Where the GDPR applies, our legal bases are: performing our contract with you, our legitimate interests in operating and securing the service, complying with legal obligations, and your consent where we ask for it.

We do not sell your personal data, and we do not use your training data to train AI models.

4. Who we share it with

Other users, as the product requires. Your coach sees the sessions you complete for the programs they assign you. Organization administrators see their organization's roster. Community posts are visible to that community. Buying a program does not put you on the seller's roster.

Service providers who process data on our behalf, under contract:

  • Supabase — database, authentication, and file storage.
  • Stripe — payments, seller onboarding, and payouts.
  • Vercel — website hosting and delivery.
  • Resend — transactional email.
  • AI model providers (currently Anthropic, OpenAI, and Google) — only the content involved in an AI request you make.
  • Apple and Google — where you subscribe through their app stores, or receive push notifications.

We may also disclose data where the law requires it, or to protect the rights and safety of our users. If the business is sold or merged, data may transfer as part of that transaction; we will say so before it happens.

5. AI features and your data

When you use an AI feature, the content needed to answer — such as the structure of the program you are working on — is sent to a model provider to generate a response. If you connect a third-party assistant over our connector, that assistant is operated by whoever provides it, under their own privacy policy, and what it can reach is limited to what your own account permissions allow. Do not put information into an AI conversation that you would not want processed by that provider.

6. How long we keep it

We keep your data while your account is active. When you delete your account we delete or anonymise personal data, except where we must keep records — payment and tax records in particular — for a legally required period. Backups are retained for a limited window and then cycle out. Content you contributed to an organization or a community may remain visible to that group where deleting it would break others' records of their own training.

7. Your rights

Depending on where you live, you may have the right to access, correct, delete, export, or restrict the use of your personal data, to object to processing based on legitimate interests, and to withdraw consent. Residents of California and other US states with comparable laws have equivalent rights, including the right not to be discriminated against for exercising them.

Much of this is self-service: profile and security settings let you change your name, email, and password, and account deletion is available from your account settings. For anything else, write to support@getgridlines.com and we will respond within the time the applicable law allows. If you are in the EEA or UK you may also complain to your local data protection authority.

8. Security

Data is encrypted in transit, access to production systems is restricted, and access to your organization's data is enforced at the database level rather than only in the interface. No system is perfectly secure; if a breach affects your personal data we will notify you and the relevant regulator where the law requires it.

9. International transfers

We and our service providers operate in the United States and elsewhere, so your data may be processed outside the country where you live. Where we transfer personal data out of the EEA or UK we rely on appropriate safeguards, such as the European Commission's standard contractual clauses.

10. Children

Gridlines is not intended for children under 16, and we do not knowingly collect their personal data. Where a coach trains minors, the coach is responsible for obtaining any consent their jurisdiction requires. If you believe a child has given us personal data, write to support@getgridlines.com and we will delete it.

11. Changes to this policy

We may update this policy. If a change is material we will give notice before it takes effect. The date at the top of this page shows when it last changed.
