Stretch 3D is a stretching app. You can use all of it without an account, and then nothing you do leaves your phone. If you choose to sign in, we back up your stretching history and custom routines so you can get them back on another phone. This page explains exactly what that means.
Who we are
Stretch 3D is made by Vireo Health Apps, the trading name of Ashley Burr, a sole trader based in the UK. We decide how your data is used, which makes us its "controller" under UK data protection law.

What we keep
If you don't sign in
Your sessions, streaks, custom routines, reminder times and settings are stored only on your phone. We never see them. Uninstalling Stretch 3D removes them.
If you sign in
Signing in is optional and is only for backup and syncing between phones. We then keep:
- Account
Your email address, or your Google account's email and name if you sign in with Google, and an account ID. If you use a password, Google's sign-in service stores it in a scrambled form; we can't see it.
- Stretching history
For each session you finish: which routine, when, how long it took and how many stretches it had. Also your streak and totals, worked out from those sessions.
- Custom routines
The name, description and stretches of any routine you build, and routines you've deleted (marked as deleted, so they don't come back on another phone).
Reminder times, display settings and timer choices always stay on your phone, even when you're signed in.
Stretch 3D Premium
Premium is a one-time purchase made through Google Play. Google handles the payment; we never see your card details. The app only learns from Google Play whether you've bought Premium.
If you email us
If you email us, for example with feedback from Stretch 3D's Settings, we keep your email address and message so we can reply and improve our apps. The feedback email includes your Stretch 3D version and phone model at the bottom, which you can delete before sending. Our lawful basis is our legitimate interests. We delete these emails after two years, or sooner if you ask.
What we don't collect
We don't ask about your health, injuries or body. Stretch 3D has no ads, no advertising ID, no analytics or tracking tools, and doesn't use your location, contacts, camera, microphone or photos.
Why we use it
We use your data only to back up your progress and routines and sync them to your other phones, which is the service you asked for when you signed in. Under UK GDPR our lawful basis is that this is necessary to provide the service (contract).
We may also look at it to fix a problem with your account or keep the service secure, on the basis of our legitimate interests, and only as far as that needs.
We don't sell your data, use it for advertising, build profiles from it, or use it to train AI. We'll only email you about your account. If we ever want to send you anything else, we'll ask first.
Who else handles it
- Google Firebase
Firebase Authentication runs sign-in and Cloud Firestore stores your backed-up data. Google does this on our behalf as our processor, under Google's data processing terms, and may not use your Stretch 3D data for its own purposes.
- Google Sign-In
If you sign in with Google, Google tells Stretch 3D your email address and name.
- Google Play
Handles downloads and the Premium purchase. Google is responsible for that data itself; see Google's privacy policy.
Where it's stored and how it's protected
Your backed-up data is stored by Google Cloud Firestore in the European Union (Google's eur3 multi-region: Belgium and the Netherlands). Google may process some data outside the UK. Where it does, it's protected by safeguards recognised under UK law, such as the UK International Data Transfer Addendum to the standard contractual clauses in Google's data processing terms.
Data is encrypted while it travels between your phone and Google, and while it's stored.
How long we keep it
We keep your backed-up data while you have an account. When you delete your account, it's deleted straight away. Data on your phone stays until you delete your account or uninstall Stretch 3D.
Deleting your account
In the app, go to Settings → Account → Delete account. After you confirm it's you, Stretch 3D deletes your account and everything backed up to it straight away, along with the synced data on that phone.
If you no longer have the app, see Delete your Stretch 3D account to ask us by email. We'll do it within one month.
Deleting your account doesn't cancel or refund Premium. Your purchase stays with your Google Play account, and you can restore it in the app.
Your rights
Under UK data protection law you can ask us to:
- give you a copy of your data
- correct data that's wrong
- delete your data
- limit how we use it, or object to how we use it
- give you your data in a format you can take to another service
Email us and we'll reply within one month. It's free.
If you're unhappy with how we've handled your data, please tell us first. You can also complain to the Information Commissioner's Office at ico.org.uk/make-a-complaint or on 0303 123 1113.
Children
Stretch 3D is for adults aged 18 and over. We don't knowingly collect data from children. If you think a child has created an account, email us and we'll delete it.
If Stretch 3D changes hands
If Stretch 3D or our business is sold or transferred, your data would move to the new owner so the app can keep working. The new owner would have to protect it in the same way and use it only for the same purposes. We'll tell you before it happens, so you can delete your account first if you'd rather not move with it.
Changes to this policy
If we change how Stretch 3D uses your data, we'll update this page and the date at the top. If the change matters, we'll tell you in the app before it takes effect.
