Privacy Policy

Effective date: 7 July 2026
Last updated: 29 July 2026

Zor ("the app", "we", "us") is a strength-training app: it helps you follow a structured training program, log your workouts, and track your recovery. This policy explains what data the app collects, why, where it is stored, and how you can delete it. We have tried to write it in plain language.

The app and this website are operated under the name Zor, and the data controller for the data described here is reachable at support@zor.training.


The short version

Data we collect

Account data

Profile data (entered during onboarding, editable later)

Training and wellness data (entered as you use the app)

This is health-and-fitness data and we treat it as sensitive: it is used only to provide the app's features to you, it is visible only to you (there are no social or sharing features), and it is protected by the security measures below.

Heart-rate data (optional, for cardio sessions)

If you use the app's paid cardio features and choose to connect a heart-rate source, the app reads your heart rate during a cardio session. There are three ways to connect one, and all of them are optional and stay off until you turn them on:

For a cardio session with heart rate, we store on our servers: the average and maximum heart rate for the session, a heart-rate reading roughly once per minute across the session, and which kind of source it came from. We use this only to measure how hard the session was and to make your recovery and training-load figures more accurate. We do not store a second-by-second stream, and we do not collect location, route, or GPS data.

This is health data and we treat it with extra care. Your heart-rate data is never used for advertising or marketing, never sold, and never shared with third parties or data brokers, and we do not store it in iCloud or any other consumer cloud service. It is kept on our own servers, attached only to your account, and used only to run the app's features for you.

It is optional, and you can turn it off at any time. You can disconnect a heart-rate source in the app, and you can revoke the app's access to Apple Health whenever you like, in the iPhone Settings app under Privacy & Security, then Health, or in the Apple Health app itself. On Android you can withdraw the app's access in the Google Health Connect app, under its app-permissions settings. The cardio features work fully without heart rate. You can also delete the heart-rate data we hold without deleting the rest of your account (see deleting your data, below).

Consent. Because heart-rate data is a special category of personal data under laws such as the UK and EU GDPR, we ask for your explicit consent in the app before the first time we store any heart-rate data. You can withdraw that consent at any time by disconnecting the source and deleting the data. Withdrawing consent does not affect anything we did while the consent was in place.

Product-interaction data (in-app choices)

To understand whether the app's features are actually helping, we keep a record of certain prompts the app showed you and how you responded. For example, when the app suggests an adjustment to your training, we record that it was shown and whether you accepted it or chose something else. This is a first-party record: it is linked to your account, kept on our own servers, and used only to improve the app for everyone. We do not use a third-party analytics service for it, we do not use it for advertising, and it is deleted with your account.

Diagnostic data (crash and error reports)

When the app hits an error or crashes, it sends us a diagnostic report so we can find and fix the problem. A report contains technical details about the failure: the error and where in the app it happened (including a technical stack trace), the app version and build, your device platform and operating-system version, and the time it happened. It is linked to your account so we can tell whether a problem is affecting one person or many. We use it only to diagnose and fix problems, never for advertising, and it is deleted with your account. These reports go to our own servers, not to a third-party crash-reporting service.

Data we do NOT collect

How we use your data

We use your data solely to provide the app:

  1. Run your account: sign you in, keep your data attached to you.
  2. Show you your own training: your program, workout history, progression charts, weekly training volume, and check-in trends.
  3. Compute your recovery and training-load metrics: the app's recovery model runs on our servers using your logged sets, check-ins, session difficulty, and session duration, and adjusts guidance (e.g. suggested weights) accordingly.
  4. Send you essential account emails: sign-up confirmation and similar account/security messages. We do not send marketing email.

We do not use your data for advertising, we do not build profiles for third parties, and we do not sell or rent your data to anyone.

Where your data is stored (service providers)

We use a small number of infrastructure providers to run the app. They process data on our behalf under their own security and privacy commitments; none of them may use your data for their own purposes.

Provider What it does Where
Cloud database & authentication provider Account authentication and our database (all data listed above) Outside your country of residence (see international transfers below)
Cloud application-hosting provider Hosts our API servers, which process your requests Outside your country of residence (see international transfers below)
Transactional email provider Delivers account emails (e.g. the sign-up confirmation code); processes your email address Outside your country of residence (see international transfers below)
Website & email-routing provider Serves this website and routes email you send to support@zor.training to our inbox (Email Routing) Outside your country of residence (see international transfers below)

International transfers: your account and training data may be processed and stored outside the country where you live. Where your data is transferred across borders, for example if you use Zor from the EU or UK, we rely on appropriate legal safeguards for such transfers, such as Standard Contractual Clauses in our providers' data-processing terms. You can request more detail about these safeguards by emailing support@zor.training.

Data in transit is encrypted (HTTPS/TLS). Access to production systems is restricted to the operator.

Data stored on your device

The app works offline: workouts and check-ins you log without an internet connection are stored on your device and synced to our servers when you are back online. Your device also caches your program and recent data so the app loads quickly. This on-device data is the same data described above, not an extra category. It is removed when you delete the app or delete your account; signing out clears your cached data too, except that workouts logged offline and not yet synced are kept on the device so they are not lost, and upload after you next sign in.

Deleting your account and your data

You can delete your account in two ways:

  1. In the app: Settings → Account → Delete account (press and hold to confirm). Deletion is immediate and permanent.
  2. By email: send a deletion request from your account email address to support@zor.training. We will verify the request came from your address and process it within 30 days.

Deleting your account deletes your authentication record and all data linked to it: profile, programs, custom exercises, workout sessions, logged sets, check-ins, soreness ratings, cardio sessions and any heart-rate data, crash and diagnostic reports, and derived strength/recovery values. This is enforced at the database level (all your data is keyed to your account and is removed with it), and the data is deleted immediately from our live database.

Backups. Our database provider takes an encrypted daily backup of the whole database so we can recover from a failure, and each backup is kept for 7 days before it is overwritten. Your data is removed from the live database immediately when you delete your account, and any remaining copy of it inside those backups ages out of the rotation within 7 days. We do not use backups to bring a deleted account back.

Deleting only your heart-rate data. If you want to remove the heart-rate data we hold but keep the rest of your account, you can do that in the app by disconnecting your heart-rate source and choosing to delete your heart-rate data. Your cardio sessions themselves stay (their duration and how hard they felt), but the stored heart-rate figures and per-minute readings are removed, and your consent is withdrawn.

Data retention

We keep your data for as long as your account exists, because the app's purpose is your long-term training history. We do not have time-based deletion of old training data; your history is the product. When you delete your account, everything goes with it (see above).

Your rights

Depending on where you live (e.g. GDPR in the EU/UK, CCPA in California), you may have rights to access, correct, export, or delete your personal data, and to complain to a supervisory authority. You can exercise access and deletion directly: the app shows you all your data, and account deletion is described above. Where we rely on your consent (for heart-rate data), you can withdraw it at any time in the app, as described above. For an export of your data, or any other request, email support@zor.training.

Children

Zor is not directed at children. You must be at least 18 to create an account. We do not knowingly collect data from children below that age; if you believe a child has created an account, contact us and we will delete it.

Not medical advice

Zor provides fitness and training information only. It is not medical advice, and it is not a medical device. The app's recovery scores, training recommendations, and any other guidance are for general fitness purposes. Consult a qualified healthcare professional before starting a training program, and stop and seek medical advice if you experience pain, injury, or other symptoms. You are responsible for training within your own limits.

Changes to this policy

If we change what we collect or how we use it, we will update this policy and change the "Last updated" date before the change takes effect, and, for significant changes, tell you in the app. In particular, if the app ever starts sharing data with a new category of provider, this policy will be updated before that happens.
