— DEADSTOP

Privacy Policy

Last updated: October 2026

DEADSTOP ("the app") is developed by Almstedt Studio. This privacy policy explains what data the app collects, how it is used, and your rights regarding that data.

1. Data We Collect

The app collects the following data:

  • Training data you enter manually (workout plans, exercises, sets, weights, reps, notes, personal records) and their dates
  • Workouts imported from Apple Health or Health Connect — optional, and only if you grant access. See section 2 for exactly what is read and how it is used.
  • Email address — only if you sign in. With email and password it is used for sign-in and password recovery; with Apple or Google it is the address that service shares (with Apple this can be a private relay address if you choose to hide yours). See section 3.
  • Account identifier — an ID assigned to your account, including when you start training without signing in (section 3). Your training data is stored under it, and it is shared with RevenueCat so the app knows whether you have Pro.
  • Purchase and trial status — whether you have Pro through a subscription or a lifetime purchase, and when your free trial started. Purchases are handled by RevenueCat and made through Apple or Google; we never see your payment details.
  • App settings — units, theme, text size, rest timer and logging preferences, your active program, your favourite exercises and your goals. These are stored with your account so the app behaves the same on every device you sign in on.
  • Body weight — optional. Only stored if you enter one, or if you let the app read it from Apple Health or Health Connect (section 2), and only used to estimate the calories burned in a session. Leave it blank and the app simply leaves that estimate out.

The app does not ask for your name, phone number or advertising identifier. If you sign in with Google, Google also shares your name and profile picture with Firebase Authentication as part of the sign-in; the app does not use or display them. The app does not track your location and never asks for location permission; the only location data it holds is the GPS route of a workout you have chosen to import from Apple Health or Health Connect (section 2).

Your gym reminder schedule is kept on your device only and is never uploaded.

2. Health Data (Apple Health / Health Connect)

DEADSTOP can import runs, rides, walks and other workouts that your watch or another app has recorded, so that they appear in your training log next to your strength sessions. On iPhone this data comes from Apple Health (HealthKit); on Android from Health Connect. This is optional: nothing is read until you turn it on, and the operating system asks for your permission first.

With your permission, the app reads the following from workouts recorded in the last 30 days:

  • Exercise sessions — the type of workout, its start and end time
  • Distance and elevation gained during the workout
  • Heart rate during the workout — kept as a simplified curve (about 60 points), the average, highest and lowest value, and the average for each kilometre
  • Active and total calories burned during the workout
  • Steps taken during the workout (walks and runs), used to show steps and cadence
  • The GPS route of the workout, shown as a map on the session

It also reads your most recent body weight — for example from a smart scale or another app that writes it to the store. Only the latest value is used: it fills in the body weight in the app's settings, which is used to estimate calories (section 1). A value you type yourself stays until a newer measurement arrives.

How it is used. Only to show the workout in your own log — its distance, time, pace, splits per kilometre, steps and cadence, heart rate and heart-rate zones, calories, elevation and route — and to count it toward your weekly goal, streak and calendar. Imported workouts are stored with your account like any other session (section 4), so they are available on every device you sign in on.

What we do not do. We do not share health data with any third party, do not use it for advertising or analytics, and do not sell it. It is never used to make decisions about you. Our use of data obtained from Health Connect complies with the Health Connect permissions policy, including its Limited Use requirements.

Writing your sessions back (optional). If you turn on "Save sessions to Apple Health / Health Connect" in the app's settings, the app writes the strength sessions you log in it to the store as a workout: the type (strength training), its start and end time, its title and, on iOS, an estimated energy figure. That is all it writes. Workouts imported from the store are never written back, and nothing is written until you turn this on. You can turn it off in the app's settings or revoke write access in the Health app / Health Connect at any time; sessions already written stay in the store until you delete them there (on Android the app removes its own record when you delete the session in the app).

Your control. You can turn automatic import off in the app's settings, revoke the app's access at any time in the Health app (iOS) or in Health Connect (Android), and delete any imported session in the app exactly like a session you logged yourself (section 8). Deleting your account deletes all imported workouts too. Revoking access does not remove data already imported; delete those sessions in the app if you want them gone.

3. Accounts and Sign-in

Without signing in. You can tap START TRAINING and use the app without giving any personal details. The app then creates an anonymous account in Firebase Authentication — an account identifier with no email, name or password — and stores your training under it (section 4). Only this installation of the app can reach that account: if you uninstall the app or clear its data without signing in, the training can no longer be recovered, and we cannot identify it for you.

Signing in. You can sign in at any time — after your first session or in Settings — with an email address and password, with Apple or with Google, all via Firebase Authentication. Signing in from an anonymous account keeps the same account identifier, so the training you have already logged stays with you and becomes available on every device you sign in on.

  • Email and password — your password is handled by Firebase and is never stored by us directly.
  • Sign in with Apple — Apple shares your email address, or a private relay address if you choose to hide yours. The app does not request your name.
  • Google — Google shares your email address, name and profile picture. Only the email address is used, to show which account you are signed in with.

4. Data Storage

Your training data is stored securely in Google Firebase Firestore, associated with your account identifier — also when you use the app without signing in. Data is stored in the European Union (europe-west1) and encrypted in transit.

5. Data Sharing

We do not sell, share, or disclose your data to any third parties, except as required by the infrastructure services listed below.

6. Third-Party Services

  • Google Firebase (Authentication, Firestore & Cloud Storage) — Privacy Policy
  • Sign in with Apple — only if you choose it — Apple Privacy Policy
  • Google Sign-In — only if you choose it — Google Privacy Policy
  • RevenueCat (in-app purchase and subscription management) — Privacy Policy
  • Apple Maps (iOS) and Google Maps (Android) — draw the map behind an imported route. To show the map, the device requests map tiles for the area of the route from Apple or Google, which therefore receive your device's IP address and the map area shown. The route itself is drawn by the app on top of the map and is not sent to them. Apple Privacy Policy · Google Privacy Policy

Cloud Storage hosts the exercise illustrations and animations. The app downloads those before you sign in, so Google receives your device's IP address for that request, the same way it would for any file downloaded from the internet. No training data is stored there.

7. Notifications

The app may schedule local notifications on your device for rest timers and reminders. These are handled by iOS or Android on your device. No notification content is sent to any server operated by Almstedt Studio.

8. Deleting Your Data

You have full control over your data and can delete it at any time:

Delete a logged session

Open the session — tap it in the calendar, or tap the last session on the home screen. Scroll to the bottom of that screen, tap Delete session and confirm.

Delete your account and all associated data (in-app)

You can delete your account directly from within the app:

  1. Open Settings
  2. Scroll to the Account section
  3. Tap Delete account
  4. Confirm and tap Delete forever. An email account asks for your password; an Apple or Google account asks you to confirm with Apple or Google; an account you never signed in to needs no confirmation.

Your account and all associated training data will be permanently deleted immediately. For an account that uses Sign in with Apple, the app also revokes the app's access to your Apple ID. Deleting the account does not cancel a subscription — cancel it in your App Store or Google Play account.

Delete your account by email (alternative)

If you cannot access the app, you can also request deletion by email. This works for accounts you have signed in to; an account you never signed in to has no email address we could match, so delete it in the app before uninstalling.

  1. Send an email to [email protected] from the email address associated with your account.
  2. Use the subject line "Delete My Account".
  3. We will permanently delete your account and all associated training data within 30 days.

What is deleted: your account, email address, all training data (plans, sessions, sets, history, imported workouts and routes), and all settings. What is kept: nothing — all data is fully removed. Anonymous purchase records may be retained by Apple or Google as required for financial/legal compliance.

9. Data Retention

We retain your data only for as long as your account remains active. Your training data is stored for as long as you use the app, so that it stays available across your devices.

Accounts created without signing in that have not been used for an extended period may be deleted, together with their data.

When you delete an entry, it is removed immediately. When you delete your account — either in the app or by email request — your account and all associated training data are permanently deleted: in the app immediately, and via email request within 30 days.

We do not retain your data after account deletion, except where required by law. Anonymous purchase records may be retained by Apple or Google as required for financial and legal compliance, as described in section 8.

10. Children's Privacy

DEADSTOP is intended for users aged 18 and over. We do not knowingly collect data from children.

11. Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
