Privacy Policy
This policy explains what Gentle Chair Exercises collects, why, and who it is shared with. It applies to the Android app distributed on Google Play. It describes the app's actual technical behaviour; it is not legal advice.
Short version
Gentle Chair Exercises guides short exercises done on or with a chair. It has no accounts and no sign-in, and we do not run any server of our own. Your Quick Start answers, your workout journal, the weight, height and water you choose to log, the sessions you edit and your settings stay on your phone and are never uploaded by the app. The app is free and supported by advertising, so our advertising partner receives your device's advertising identifier and technical device information in order to serve and measure ads, and Google Firebase receives usage events and crash reports that contain none of your fitness information. VIP subscribers see no ads.
1. Your workouts, progress and weight
The fitness information you create in the app is kept only in the app's private storage on your phone:
- Quick Start answers — only if you answer these optional first questions: your age range (under 55, 55 to 64, 65 to 74, or 75 or older), how you move today (you stand up easily, you stand with support, or you stay seated) and what would help you most (feeling less stiff, strength for daily tasks, steadier on your feet, or short breaks in your day). Your answer about how you move decides whether sessions keep every move in the chair; until you answer it, the app suggests seated moves only. The other two answers are kept so you can see and change them in Quick Start.
- Workout journal and progress — for each finished session, the date, which session it was, your active time, the number of moves you finished and the estimated calories (taken from the session's own estimate, not from your body). It is used for the Journal, your week and streak on the Today screen, and your progress through the 30-day plan, the 21-day challenges and the daily True or False quiz.
- Weight, height and water — only if you choose to log them on the Weight & Water screen: the date and the weight you enter, your height, and how many cups of water you marked today, shown in kg and cm or lb and ft. They are used for the weight chart, your BMI (a rough guide, not a diagnosis) and today's water count.
- A session in progress — which session it was and how many moves you finished, so you can continue later.
- Your changes to sessions — if you edit a session's moves, swap a move because of pain or choose to skip a move in future plans, and how a session felt when you answer "How did that feel?", which adjusts the move times of the 30-day plan.
None of this is sent to us, to our advertising or analytics partners, or to any other server, and it is never included in the usage events or crash reports described in section 3. The app does not connect to Google Fit, Health Connect or any other health service, and it does not use your phone's sensors, camera or microphone to follow your movements.
If Android backup is turned on for your Google account, Android may include the app's stored data in your device backup so that it can be restored on a new phone. That backup is made and kept by Google under your account's backup settings, and we cannot access it. You can turn backup off in your phone's settings.
2. Other information kept on your device
The app also keeps on your phone: whether you have finished Quick Start; whether the workout reminder, the water reminder and Quiet at night are on, and the workout reminder's time; whether Voice coach, Background music and "Play with music from other apps" are on; whether Large text and Warm-up & cool-down are on; your language and units; your advertising consent choices (stored by Google's consent tool); whether you have an active VIP subscription, as last reported by Google Play; until when ads are off after you watch a reward ad, and how many times you did that today; that you accepted the Terms of Use and this policy on first launch; and how many times you have opened the app, when the rating card was shown and when the last full-screen ad was shown, which are used to decide when to ask for a rating, when to show the VIP offer and to keep full-screen ads infrequent. None of this is uploaded to us. Uninstalling the app or clearing its data removes it.
3. Information collected automatically
When you use the app, our partners collect:
- Advertising ID and ad interaction data (ad requests, impressions, clicks) — used to serve and measure ads and to prevent ad fraud. Collected by Google AdMob.
- Device and app information (device model, operating system version, language, country, app version, performance information about the app and the advertising SDK) — used for ad delivery, compatibility and diagnostics. Collected by Google AdMob and Firebase.
- Approximate location derived from your IP address (country or region level, never GPS) — used for ad relevance and to apply the correct consent rules. Collected by Google AdMob. The app itself does not request any location permission.
- App usage events (for example app opens, sessions and screens viewed, whether the VIP screen was opened and whether its prices loaded, and each ad shown with its format, its place in the app and its estimated revenue) — used to understand how the app is used. Collected by Firebase Analytics, which also reads how the app was installed (the Google Play install referrer).
- Purchase events (which VIP plan was bought, its price and currency) — used to count sales. Sent to Firebase Analytics. Your payment details are never involved (see section 7).
- Crash reports and diagnostics (the error and where it happened in the app's code, short technical messages when something fails, for example loading an ad, a purchase, the coach voice or a reminder, device model, operating system version, app version and an installation identifier) — used to find and fix bugs. Collected by Firebase Crashlytics.
The app does not collect your name, email address, contacts, photos, files, microphone or camera data, or GPS location, and it does not request location, contacts, camera, microphone, storage, body sensor or phone permissions.
4. Coach voice, music, reminders and ratings
- Voice coach — when Voice coach is on, the app passes short cues, such as move names, counts and rest, to the text-to-speech engine installed on your phone (for example Google's speech services). That engine is part of your phone and works under its provider's own terms; the app sends nothing to us. You can turn the voice off in Settings or with the speaker button on the workout screen.
- Background music — generated by the app on your phone; nothing is downloaded or streamed. You can turn it off in Settings or with the music button on the workout screen.
- Reminders — both are off until you turn them on in Settings: a workout reminder on Monday, Wednesday and Friday at the time you choose, and a water reminder every 2 hours from 9 AM. With Quiet at night on, no reminder is shown from 9 PM to 8 AM. Reminders are scheduled on your phone and nothing is sent to a server. If notifications for the app are turned off in Android settings, no reminder is shown.
- Rating card — from the second time you open the app, it may show Google Play's in-app rating card. Your rating and review go to Google Play under Google's terms; the app only remembers when the card was shown.
5. Permissions and why they are used
- Internet — loads ads, sends the usage events and crash reports described in section 3, and lets Google Play handle subscriptions. Your fitness information is never sent.
- Network state — used by the advertising SDK to check whether a connection is available before loading ads.
- Notifications (Android 13 and later) — shows the workout and water reminders. It is requested only when you turn a reminder on in Settings; you can refuse and still use every workout.
- Run at startup — puts back the reminders you turned on after your phone restarts, the app is updated, or the time or time zone changes. It does nothing while both reminders are off.
- Advertising ID and Android's ad privacy features — declared by the Google Mobile Ads SDK and Firebase so they can read the advertising ID and, on Android versions that offer them, use Android's privacy-preserving advertising APIs; you control these in your device's ad privacy settings.
- Install referrer — declared by Google's libraries to tell how the app was installed (for example from Google Play).
- Foreground service and wake lock — declared by Google's libraries, which use Android's background task scheduler to send their data efficiently. The app itself runs no background service and shows no ongoing notification.
- Billing — processes the VIP subscription through Google Play.
6. Advertising and your choices
Ads are provided by Google AdMob: a banner on the Today screen and on the True or False question screen; an ad inside the session library, the session details screen, the quiz answer screen and the Journal; a full-screen ad that may appear after you finish a session or a challenge day; and an ad that may appear when you come back to the app after leaving it. In Settings you can choose to watch a reward ad to turn ads off for 2 hours. No ads are shown while a workout is running. Google may use your advertising ID to show personalised ads. VIP subscribers see no ads.
- In the European Economic Area, the United Kingdom and Switzerland, we ask for your consent before serving personalised ads, using Google's User Messaging Platform. You can change your choice at any time in the app under Settings → Privacy options.
- Anywhere, you can reset or delete your advertising ID in Android Settings → Google → Ads (or Settings → Privacy → Ads on some devices), which stops the advertising ID from being used to build a profile.
- California residents: sharing advertising identifiers with ad partners for targeted advertising may qualify as "sharing" under the CCPA/CPRA. You can opt out with the same in-app privacy controls or by resetting your advertising ID.

7. Purchases
The VIP subscription is sold and billed by Google Play. We never see or store your payment card, bank details or billing address. Google processes the payment and tells the app only whether an active purchase exists; the app records a purchase event (plan, price, currency) in Firebase Analytics as described in section 3.
8. Children
Gentle Chair Exercises is meant for adults. It is not directed to children under 13 (or the equivalent minimum age in your country) and we do not knowingly collect data from them. If you believe a child has used the app and provided data, contact us and we will help remove it.
9. Data retention and deletion
We do not maintain user accounts, so there is no profile to delete. Your Quick Start answers, workout journal, weight, height and water entries, session changes and settings stay on your phone until you clear the app's data (Android Settings → Apps → Gentle Chair Exercises → Storage → Clear storage; the names vary by phone) or uninstall the app; a copy in your Android backup follows your Google account's backup settings. Data held by our advertising and analytics partners is retained according to their own policies, linked above; you can limit it by resetting your advertising ID. Emails you send us are kept only as long as needed to answer them. To ask about data associated with your device, email hanhnt3009.ffh4x.publish@gmail.com and we will respond within 30 days.
10. Your rights
Depending on where you live, you may have the right to access, correct, delete, or restrict processing of your personal data, to object to processing, and to lodge a complaint with your data protection authority. Because we do not hold accounts, most requests are best directed to the partner holding the data, but you can always contact us first at hanhnt3009.ffh4x.publish@gmail.com.
11. Security
Data sent to our partners travels over encrypted connections. Your fitness information stays in the app's private storage on your phone, which other apps cannot read. No method of transmission or storage is completely secure, but we limit collection to what the app actually needs.
12. Changes to this policy
If this policy changes materially, we will update this page and change the effective date above. Continuing to use the app after an update means you accept the revised policy.
13. Contact
Sensi Tech, CC Đồng Phát, Hà Nội 11700, Vietnam — hanhnt3009.ffh4x.publish@gmail.com. If you email us, we receive your email address and whatever you write, and use them only to answer you.
