Sahas: Home & Gym Workouts (iOS)
Effective date: 5 October 2026 · Last updated: 1 October 2026

1. Summary

• Your data stays on your device. Sahas has no accounts. Everything you enter is stored locally on your iPhone. The one exception is the optional AI Coach (Sahas Pro): when you message it, your message and a short training summary are sent to generate the reply, not stored and not used for tracking (see "AI Coach and Autopilot" below).
• We don't sell or share your personal data. We can't see your profile, workouts, body stats or food log.
• No ads, no analytics, no tracking. Sahas contains no advertising, analytics or crash reporting software, and it doesn't track you across other companies' apps or websites.
• Subscriptions are handled by Apple. We never receive your payment details.
• Optional iCloud Sync is end-to-end encrypted. If you turn it on, your data syncs between your own devices through your private iCloud, encrypted with a key only your devices hold. We can't read it.
• Location, Apple Health and heart rate stay on your iPhone. Run routes, Apple Health data and Bluetooth heart rate readings are used on your device only and are never uploaded.
• You're in control. You can erase all Sahas data at any time from Profile, or by deleting the app.

2. Who we are

Sahas ("Sahas", "we", "us") is published by AB Labs, a trading name of Tapas Mahanta, an individual based in India. Contact: mahantaabhayy@gmail.com.

3. Information you enter in the app

To build your plan and show your progress, Sahas asks for and stores the following on your device only:

• Profile: the name you choose to be greeted by, your goal, where you train (home, gym or both), your equipment, training days, session length and experience level.
• Age (required): used to apply age-appropriate safety rules and our minimum age of 13.
• Body details (optional): sex, height and weight, used to calculate calorie and macro targets and your BMI on your device.
• Health screening answers: plain yes/no answers about conditions such as a heart condition, high blood pressure, diabetes, joint problems, breathing conditions, regular medication, dizziness, recent surgery or pregnancy, plus whether your doctor has cleared you for regular exercise. They're encrypted on your device, kept separate from your profile, used only to make your plan more cautious, never used for advertising, never shared, and never sent to the AI coach unless you explicitly turn that on. Change or clear them in Profile > Health & safety.
• Workout activity: workouts completed, exercises, sets, reps, weights, effort ratings (RPE), duration, personal records and body weight entries.
• Food log: the foods and quantities you log, and the text you type to log them. This text is interpreted on your device and is never sent anywhere.

Location (optional, runs, walks and rides)

• Sahas asks for your location only when you start an outdoor run, walk or ride, with "While Using the App" permission. It never asks for "Always".
• Your location is used only during that recording, to measure distance, pace, splits and elevation and to draw your route. If you lock your screen mid-run, the recording keeps going in the background and iOS shows the blue location indicator. Location use stops as soon as you end the recording.
• Your route is stored encrypted on your device. It isn't synced to iCloud, isn't sent to the AI Coach and is never uploaded to us or anyone else. When you open a saved route, Apple Maps provides the map image for that area.
• Indoor sessions need no location, and you can turn location off in iOS Settings at any time.

Apple Health (optional)

If you connect Apple Health (Profile > Connected devices & Health > Apple Health), Sahas asks your permission for each type and then:

• saves your completed workouts, runs, walks and rides, with duration, an energy estimate, heart rate from your sensor and, for runs, walks and rides, the distance (never the route);
• reads your weight, height, steps, heart rate, resting heart rate, heart rate variability, VO2 max, active energy, sleep and workouts from other apps, plus the names of the apps and devices that recorded them, to keep your plan, Readiness, recovery and progress accurate.

Apple Health data stays on your device. It's stored encrypted, isn't synced to iCloud, isn't sent to us, the AI Coach or anyone else, and is never used for advertising or marketing or sold. Change permissions any time in the Health app or iOS Settings; Disconnect in Sahas deletes what Sahas copied from Health.

Bluetooth heart rate (optional)

Sahas uses Bluetooth only to connect a heart rate strap or watch you choose, while you pair it or during a workout or run. Readings stay on your device and aren't sent to us or the AI Coach.

This information is saved in the app's local storage on your iPhone. It isn't transmitted to us or to any third party. If your iPhone backs up app data to iCloud or to a computer, that backup is controlled by Apple and by you under Apple's terms, and we can't access it.

iCloud Sync (optional)

iCloud Sync keeps your Sahas data the same on the iPhones and iPads signed in to your Apple Account. It uses your own private iCloud database (Apple CloudKit), which is part of your Apple Account, not a Sahas server; we have no access to it.

• End-to-end encrypted: everything is encrypted on your device (AES-256-GCM) before it's uploaded, with a key stored only on your devices and in your iCloud Keychain, which Apple end-to-end encrypts. Record names and change details are encrypted too. Neither we nor Apple can read your Sahas data in iCloud.
• What syncs: your profile and body details, plan, saved exercises, workouts and sets, progression, body weight, food log, diet preferences, coach chat and health screening answers. Your subscription status, Apple Health and heart rate sensor data, run routes and display settings stay on each device.
• Your control: Profile > iCloud Sync shows the status and lets you turn it off (your data stays on the device). Delete all my data asks whether to delete on this device only or on all your devices, including the copy in your iCloud.
• Availability: needs an iCloud account and iCloud Keychain. The current version shows "Unavailable in this build" until iCloud is enabled in a future update.

Because this data stays in your own iCloud and we can't access it, we don't collect it, and the App Store label remains "Data Not Collected".

AI Coach and Autopilot (Sahas Pro)

The AI Coach is the only part of Sahas that sends information off your device, and only when you send it a message.

• What is sent: the message you type, up to six earlier messages from the same chat, and a short summary of your training settings (your goal, level, where you train, training days, session length, equipment, muscles to avoid, the exercises in the workout you are asking about, how many sessions you did in the last 14 days, your average effort and days since your last session, and your diet type and meals a day). It goes over an encrypted connection to the Sahas coach server (hosted on Cloudflare) and to our AI provider, Anthropic, to generate the reply.
• Body stats only if you opt in: your weight, height and age are included only if you turn on "Share body stats with the coach" (off by default).
• Health: if you told Sahas about a health condition, we only send the fact that you did (yes or no), never which condition or medication. We never send your name or email, your health screening answers, Apple Health data, heart rate readings, your location or routes, your logged sets or your food log.
• Subscription check: to confirm Sahas Pro, the app sends the Apple-signed transaction for your subscription. We check it with Apple and don't receive your Apple ID, name or email.
• What we keep: only a daily and monthly message count and your weekly report text, stored under a one-way code derived from the transaction and deleted automatically (reports within 14 days, counters within 40 days). We don't store or log your messages. Anthropic processes the request to generate the reply under its commercial terms and doesn't use it to train its models.
• Not used for tracking: coach data is used only to answer you. It isn't used for advertising or analytics, isn't combined with other data, isn't sold, and isn't linked to you beyond the subscription check and the message limits.
• Autopilot runs entirely on your device. It changes your plan only through the Sahas workout engine, logs every change in Activity where you can undo it, and asks before any calorie change.
• Your chat history, Activity log and coach settings are encrypted on your device, included in Export my data and removed by Delete all my data.
• AI can make mistakes. The coach gives general fitness guidance, not medical advice.

4. Information we don't collect

Sahas doesn't access your contacts, photos, camera, microphone or advertising identifier. Your location (only while recording an outdoor activity), Apple Health data and Bluetooth heart rate readings are used on your device only and are never sent to us or to the AI Coach, so we don't collect them.

5. Purchases and subscriptions

Sahas Pro is sold through Apple's App Store using Apple in-app purchase. Apple processes your payment and manages your subscription under the Apple Media Services Terms and Conditions and Apple's Privacy Policy. We don't receive or store your name, email address, or payment card details. The app checks with the App Store on your device whether you have an active subscription so it can unlock Sahas Pro. Apple may provide us with aggregated, non-identifying sales and subscription reports.

6. How we use information

Apart from AI Coach requests, your information stays on your device and is used only by the app, on your device, to:

• generate and adapt your workouts and weekly plan;
• show your progress, streaks and records;
• calculate nutrition targets and keep your food log;
• unlock Sahas Pro when you have an active subscription.

7. Sharing

We don't sell, rent or share your personal information, and we don't share it for cross-context behavioral advertising. The only service providers that process data for us are Anthropic (our AI provider) and Cloudflare (which hosts the coach server), and only for AI Coach requests, as described above.

If you email us for support, we'll receive your email address and whatever you choose to include in your message. We use it only to respond to you and keep it for no longer than needed for that purpose, up to 24 months, unless the law requires otherwise.

8. Retention and deletion

• Data stays on your device until you delete it.
• Profile > Export my data gives you a copy of all your Sahas data as a JSON file, through the iOS share sheet.
• Profile > Delete all my data permanently erases all Sahas data on your device and returns the app to onboarding. With iCloud Sync on, you choose between this device only and all your devices (which also deletes the copy in your private iCloud and the sync key).
• Deleting the Sahas app also removes its data from your device.
• Cancelling Sahas Pro doesn't delete your data; see Support for how to cancel.

9. Your rights

Depending on where you live, you may have rights to access, correct, delete or port your personal data, to withdraw consent and to complain to a data protection authority. We hold almost no personal data from the app (only the short-lived AI Coach counters and weekly report described above, under a one-way code), so you can exercise these rights directly on your device (view and edit your details in the app, export them with Export my data, or erase them with Delete all my data). For any request or question, including about support emails we hold, contact mahantaabhayy@gmail.com. Grievance officer (India): Tapas Mahanta, mahantaabhayy@gmail.com. We aim to respond within 30 days.

10. Children

Sahas is for people aged 13 and over. Onboarding asks your age and doesn't let anyone under 13 continue; nothing they enter is saved. Users aged 13 to 17 may use Sahas only with the consent of a parent or guardian. We don't knowingly collect personal data from children under 13, and because the app doesn't send data to us, we don't receive children's data through the app.

11. Security

Your data is protected by your iPhone's security, including your passcode and device encryption, and Sahas encrypts it again with its own key. Apart from AI Coach messages (sent over HTTPS and not stored), Sahas doesn't transmit your data to us; with iCloud Sync on, it's sent only to your own private iCloud, end-to-end encrypted. Keep your device secure and up to date.

12. Health and safety

Sahas is designed to help people stay active. It provides general fitness and nutrition information and isn't medical advice. Consult your doctor before starting a new exercise or nutrition program, and if you take medication for blood pressure, diabetes or any other condition, speak to your doctor before changing your exercise or diet. See the Terms of Use.

13. Changes to this policy

If we add features that change how data is handled, for example optional accounts and backup, uploading routes, analytics or crash reporting, we'll update this policy and the App Store privacy details before releasing that feature, and tell you in the app when a change is material. The "Last updated" date above shows the latest version.
