Privacy Policy
This policy explains what the Glassfold app (package com.scaleus.glassfold) and this website collect, why, how long we keep it, and the choices you have. The data controller is Scale Us Technologies LLP, Indore, Madhya Pradesh, India ("Scale Us", "we"). Contact: privacy@scaleus.in.
1. The short version
- The picture of your screen used to draw the fold animation is processed on your phone, in memory only. It is never saved to storage and never sent to us or anyone else.
- We collect basic device information so the app works on your model, plus anonymous usage events so we can improve it.
- An account (email and name) is optional. You can skip it.
- Ads are served by Google AdMob, with consent asked where the law requires it. Pro subscribers see no ads.
- You can delete your account and data at any time from the app or at glassfold.scaleus.in/delete-account.
2. What we collect
| Data | Details | Why |
|---|---|---|
| Device information | A random install ID generated by the app, device brand, model and codename, Android version and SDK level, screen size, whether it is a foldable and which hinge sensor it has, app version, language/locale, time zone, the country setting of the phone, and the install referrer. | To make the effect work correctly on your hardware, to count installs, and to fix model-specific problems. |
| Network information | When the app contacts our server we see your IP address. We store only a shortened network prefix (the last part removed, e.g. 203.0.113.0/24), never the full address, and we clear it 30 days after it was last seen. | Abuse prevention and rough country statistics. |
| Account (optional) | Email address, name, sign-in method (email or Google), and whether you agreed to receive product news. With Google sign-in we receive your Google account ID, email and name from Google. | To keep your Pro access across phones and, only if you opt in, to send product news. |
| Purchase status | Subscription product, base plan, Google Play order ID and purchase token, purchase and expiry time, and the subscription state reported by Google Play. | To unlock Pro and verify that a subscription is genuine. |
| Usage events | App actions such as opening the app, choosing an effect, viewing the paywall, starting a purchase, or enabling the service, with technical properties (for example the effect name or hinge angle range). | To understand which effects people use and to improve the app. |
We do not collect your contacts, files, photos, messages, precise location, or anything you type in other apps.
3. Accessibility service
Glassfold offers an optional Android Accessibility service. It is used for exactly two things: (a) detecting when your phone is folded or unfolded and which screen is active, and (b) taking a single picture of the current screen at that moment (Android's takeScreenshot) so the animation can show your real screen moving "through glass". That picture is held in memory for the length of the animation and then discarded. It is never written to storage, never uploaded, and never shared. The service does not read text, record your activity, or interact with other apps. You can turn it off at any time in Android Settings → Accessibility, or use wallpaper mode, which needs no special permission.
4. Advertising and consent
The free version shows ads from Google AdMob, including optional rewarded ads that unlock a Pro effect for 24 hours. AdMob may use your device's advertising ID and similar data to show and measure ads. In the European Economic Area, the United Kingdom and Switzerland we ask for your consent using Google's User Messaging Platform (UMP) before personalised ads are shown, and you can change your choice from the app's settings. You can also reset or delete your advertising ID in Android Settings → Privacy → Ads. See how Google uses data from partner apps.
5. Payments
Subscriptions are sold and charged by Google Play Billing. We never see your card or payment details. Google tells us the subscription status so we can unlock Pro, and our server may confirm it with the Google Play Developer API.
6. Who we share data with
- Google — AdMob (ads), Google Play Billing (payments), Google Sign-In (if you choose it).
- Our hosting provider — the server that runs this website and API, under contract and on our instructions only.
- Authorities — only when required by law.
We do not sell personal data. If you opt in to product news, we may use your email address to show you Glassfold or Scale Us offers on advertising platforms (for example via a hashed customer list); you can withdraw that consent at any time.
7. How long we keep data
- Network prefix: 30 days after it was last seen.
- Usage events: 13 months.
- Device information: while the app is in use, and up to 24 months after the device last contacted us.
- Account: until you delete it.
- Purchase records: as long as required by Indian tax and accounting law (up to 8 years), with personal details removed once your account is deleted.
8. Deleting your data
Use Settings → Delete account in the app, or the form at glassfold.scaleus.in/delete-account, or email privacy@scaleus.in. We delete your account (email, name, Google ID, marketing consent), the usage events of devices linked to it, and the network data of those devices within 30 days. Purchase records are kept only as required by law and are unlinked from you. Uninstalling the app does not cancel a subscription — cancel it in Google Play → Payments & subscriptions.
9. Your rights
Depending on where you live (for example under the EU/UK GDPR or India's Digital Personal Data Protection Act, 2023) you may have the right to access, correct, delete or export your data, to object to or restrict processing, to withdraw consent, and to complain to a data-protection authority. Write to privacy@scaleus.in and we will respond within 30 days. Our legal bases are: performing our contract with you (running the app and Pro), our legitimate interests (security, statistics, improving the app), and your consent (marketing emails and, where required, personalised ads).
10. International transfers and security
Data may be processed in India and in other countries where our providers operate. We protect it with encryption in transit (HTTPS), hashed access tokens, signed entitlements, restricted server access and the minimum data needed.
11. Children
Glassfold is not directed at children under 13 (or the minimum age in your country) and we do not knowingly collect their data. If you believe a child has given us data, contact us and we will delete it.
12. Changes
We will post any change on this page and update the effective date. Material changes will also be shown in the app.
