Privacy Policy
Effective as of 9 November 2026
Desk Stretches is based in Switzerland. We follow the Swiss Federal Act on Data Protection and the GDPR, wherever you use the app.
This policy explains how we handle your data. Here's the short version. The full policy follows.
Data that helps to serve you. When you use Desk Stretches, we collect data to make your experience better. This includes keeping the app working reliably, understanding which routines help people most, and giving you the right routine at the right time.
Linked to you while you use the app, anonymous after. We record how you use the app, linked to your phone and your account, so we can improve it and understand what helps. When you delete your account, or stop using the app for two years, we remove everything that links that record to you. What remains can't be traced to you by us or anyone else.
Your account. You can use Desk Stretches without an account. After a few resets, the app asks whether you'd like a free one; you can say not now and keep going. When you create one, you agree to our Terms of Use and this Privacy Policy. An account keeps your routine history safe so you can pick up where you left off on a new phone. If you delete your account, your email, history and settings go straight away, and your usage record is made anonymous within a day.
You're in control. You can access, change, or delete your personal data at any time by emailing us. If you gave us consent, you can take it back at any point.
1. Who we are
Desk Stretches is made by Delfim de Almeida, Altstetterstrasse 152, 8048 Zurich, Switzerland ("we", "us"). We are the data controller for the app. Contact: delfimjoaoalmeida+deskstretches@gmail.com.
2. What we collect
Your account (optional; the app asks after a few resets): your email address, and your routine history and settings so they follow you to a new phone, including how each routine felt. Signing in uses a code we email you; there is no password.
Emails from us: if you tick "Send me tips and news by email", we use your email address to send you tips, new routines, offers and news about Desk Stretches, and record when you said yes. You can stop at any time in Settings or with the link in any email.
About you: if you answer the questions when you start, how long you sit on a workday, what you feel by the end of the day (for example a stiff neck or tired eyes), your age range, gender, whether you work in an office, at home or both, and whether you can stand at your desk.
Where you are: the country, region and city your internet connection comes from, worked out by our server from your internet (IP) address when the app sends usage data. We keep the place, not the address.
How the app is used: when you open and leave the app and for how long; which screens you see, how long you stay and how far you scroll; the buttons and switches you use and where on the screen you touch; which routines you start, finish, pause or skip, movement by movement; reminders planned, tapped or skipped; your settings, including your exact work hours; links that opened the app; and where you installed it from (the store's campaign information).
About your phone: the app version, device make and model and its approximate age, operating system, version and build, memory, screen size and pixel density, the languages set on it, region, time zone, currency, measurement units and clock format, and when the app was installed and last updated; once per session, the battery level and power-saving settings, network type and airplane mode, free and total storage (Android only), whether notifications are allowed and Do Not Disturb, how many notifications are waiting, and whether the phone is rooted; and on Android, the phone's Android ID, which stays the same if you reinstall the app. Each record also carries a random identifier created on your phone, and your account number once you are signed in. Never your name or email.
Before you say yes: until you agree to the Terms when you create an account, or turn on "Link my use to me" in Settings › Privacy, how you use the app is counted anonymously: what the app sends carries no Android ID, no account number, nothing about where you installed it from and none of your About you answers, and we do not look up where you are. Your About you answers stay on your phone until then. You can turn "Link my use to me" off at any time; how the app is used is then counted anonymously again.
Health data: if you tell us a routine left you feeling better, the same or worse; how much your phone moves during each movement, measured by its motion sensor; and your accessibility settings (screen reader, text size, bold text, contrast, reduced motion, reduced transparency, grayscale, inverted colours, and on Android whether any accessibility service is on), because these can say something about your health. You give us permission for this with its own tick when you create your account ("Use how routines felt to improve my suggestions"); you can withdraw it at any time in Settings.
When something goes wrong, and how fast the app is: crash and error reports, performance measurements (how quickly screens open and whether they stutter), and, for a session where an error happens, a screen recording in which all text, images and icons are masked, so we can see where the app got stuck without seeing what was on screen.
Ads: the free version of Desk Stretches can show ads from Google AdMob. To show and measure them, Google collects your phone's advertising ID, your approximate location, information about your phone, and how you interact with the ads. Where the law requires it, Google asks for your permission first; you can change your choice at any time in Settings › Ad privacy choices. Buying Desk Stretches Full removes all ads. Google's own privacy policy applies to the data it collects: policies.google.com/privacy.
Purchases: Google Play handles payment for Desk Stretches Full. We receive that you bought it and a purchase reference, never your card or bank details.
We do not collect your precise (GPS) location, contacts, photos, microphone, camera, or anything from other apps.
3. Why we collect it, and on what basis
| What | Why | Legal basis |
|---|---|---|
| Email, history, settings | To run your account and sync your history | Our contract with you |
| How the app is used, and about your phone | To improve routines, reminders and the app itself; to understand where people come from and what keeps them; to produce anonymised statistics | Our legitimate interest in improving the app and growing the business (turn off "Link my use to me" in Settings › Privacy to make it anonymous, or object by emailing us) |
| Emails from us | To send you tips, new routines, offers and news | Your consent, given with the tick (withdraw it in Settings or by unsubscribing) |
| About you | To fit routines and content to the people who use them, and to understand who uses the app | Your consent, by answering (each question is optional) |
| Where you are | To understand where the app is used, plan languages, prices and marketing, and produce statistics | Our legitimate interest in growing the business, only after you agree to the Terms or turn on "Link my use to me" (turn it off in Settings › Privacy, or object by emailing us) |
| Ads | To keep a free version of the app | Your consent where the law requires it (Google's consent form), otherwise our legitimate interest in funding the app |
| Health data | To learn which routines help and whether people really move, and for anonymised research and statistics | Your explicit consent, given with its own tick at sign-up (withdraw it in Settings) |
| Crash reports, performance, masked screen recordings | To keep the app working and fast | Our legitimate interest in a reliable app |
We never sell your personal data.
Health data is never used for advertising and is never shared with advertisers, data brokers or resellers.
4. Anonymised data
We combine usage data into statistics that cannot be traced to any person: for example, how often desk workers finish a two-minute neck routine, or at what time of day breaks happen. These statistics are not personal data. We may publish them, share or sell them, for example to research partners, or use them in products for employers and organisations. They never contain names, emails, device identifiers or anything else that points to an individual, and we will never try to reverse them.
5. Who else sees your data
These companies process data on our behalf, under contract, and only on our instructions:
- Appwrite (Frankfurt, Germany): hosts accounts, history and usage data.
- Sentry (EU region): receives crash and error reports, performance measurements and masked screen recordings.
- MaxMind (United States): turns your internet address into a country, region and city when the app sends usage data. It receives the address only for that lookup.
- Our email service (named here when we choose it): sends the emails you asked for.
Google shows any ads in the free version (AdMob) and handles purchases (Google Play), as described in section 2, under Google's own terms and privacy policy.
Your account, history and usage data are stored in the European Union, which Switzerland recognises as providing adequate protection. Where a company above processes data in the United States, it does so under its data protection terms with us. We share personal data with no one else, except if the law requires it.
6. How long we keep it
- Account, history and settings: until you delete your account.
- Usage and health data linked to you: as long as you use the app. It is made anonymous when you delete your account (within a day), or once neither your account nor your phone has used the app for 24 months.
- Emails from us: until you unsubscribe or delete your account.
- Anonymised data and statistics: kept, because they no longer point to anyone.
- Crash reports, performance data and screen recordings: 90 days.
On your phone. Your history and settings are also stored on your phone so the app works without a connection. Signing out first sends anything not yet saved to your account, then removes this copy from the phone; so does deleting everything on this phone in Settings, which also signs you out. Android does not back this copy up. On an iPhone it is part of your iCloud or computer backup, as other apps' data is, so a restored iPhone keeps your history.
7. Your rights
You can ask us at any time to show you the personal data we hold, correct it, delete it, or send you a copy. You can withdraw any consent you gave. You can make usage data anonymous at any time by turning off "Link my use to me" in Settings › Privacy, or object to it by emailing us at the address below. To delete your account, use Settings in the app or visit deskstretches.pages.dev/delete; deletion removes your email, history and settings at once, and makes your usage and health data anonymous within a day, including what was recorded on your phone before you signed in.
Email delfimjoaoalmeida+deskstretches@gmail.com. We answer within one month. If you are not satisfied, you can complain to the Swiss Federal Data Protection and Information Commissioner or to your local data protection authority.
8. Children
Desk Stretches is for people aged 16 and over.
9. Changes
We review this policy at least once a year. If something important changes, we will tell you in the app.
