Privacy Policy
1. Who we are
Craftly: DIY Wallpaper ("Craftly", "the app") is published by EXO Studio, Hanoi, Vietnam ("we", "us"). This policy explains what information the app handles on iPhone and why. Contact: exostudio.feedback@gmail.com.
2. Information we collect
Your photos and designs stay on your device. Craftly has no account or sign-in and does not upload your photos, designs, text, or exported wallpapers to our servers.
The app uses third-party SDKs that collect limited technical information automatically:
| Category | Examples | Collected by |
|---|---|---|
| Device and app information | Device model, OS version, app version, language, country/region derived from IP | Firebase, Google Mobile Ads |
| Identifiers | Firebase installation ID, app instance ID; Advertising Identifier (IDFA) only if you allow tracking | Firebase, Google Mobile Ads |
| Usage data | Screens opened, features used, ad impressions and clicks | Firebase Analytics, Google Mobile Ads |
| Diagnostics | Crash logs, stack traces, device state at crash | Firebase Crashlytics |
| Purchases | Subscription or purchase status (no card details) | Apple (App Store / StoreKit) |
3. How your information is processed
On-device only: photos you pick through the iOS photo picker, templates, stickers, text, drafts, favorites, and exported wallpapers are processed and stored locally in the app. Saving a wallpaper writes the image to your Photos library only when you tap save and grant permission.
Sent to service providers: the technical data in the table above is sent to Google (Firebase and Google Mobile Ads) to measure usage, fix crashes, configure features remotely, and show ads. Purchases are processed by Apple.
4. Purposes and legal bases
- Provide the app and its features — performance of our agreement with you.
- Analytics and crash diagnostics to improve stability and quality — legitimate interests.
- Remote configuration of features and ad frequency — legitimate interests.
- Showing ads that keep core features free — consent where required (personalized ads, tracking) or legitimate interests (non-personalized ads).
- Unlocking premium features you buy — performance of our agreement with you.
5. Service providers and SDKs
| Provider | Purpose | Policy |
|---|---|---|
| Google Firebase (Analytics, Crashlytics, Remote Config) | Usage analytics, crash reports, remote settings | firebase.google.com/support/privacy |
| Google Mobile Ads SDK (AdMob) and User Messaging Platform | Ads and consent management | policies.google.com/technologies/partner-sites |
| Apple (App Store, StoreKit) | Subscriptions and purchases | apple.com/legal/privacy |
6. Ads, consent, and tracking
Free users may see ads (app open, interstitial, rewarded, and native ads). Where required (for example in the EEA, UK, and Switzerland), we show a consent form from Google's User Messaging Platform before ads are requested. Afterwards, iOS may ask whether Craftly may track you across other companies' apps and websites (App Tracking Transparency). If you decline, the IDFA is not shared and ads may be less relevant. You can change these choices at any time in iOS Settings → Privacy & Security → Tracking, and through the privacy options in the app where available.
Premium subscribers and lifetime owners do not see ads.
7. Sharing and sale
We do not sell your personal information and we do not share your photos or designs. Technical data is shared only with the providers listed above for the stated purposes, or when required by law.
8. Retention
Your designs and drafts remain on your device until you delete them or remove the app. Firebase Analytics data is retained for up to 14 months; crash reports are retained for up to 90 days; ad providers retain data according to their own policies.
9. Security
Local data is stored in the app's sandbox and protected by iOS. Data sent to providers is transmitted over encrypted connections. No method of storage or transmission is completely secure.
10. Device permissions
- Photos (select): to place photos you choose into your designs. You can limit access to selected photos.
- Photos (add only): to save exported wallpapers to your library.
- Tracking (App Tracking Transparency): optional, used only for ad personalization.
11. Children
Craftly is not directed to children under 13 (or the minimum age in your country). We do not knowingly collect personal information from children. If you believe a child has provided information, contact us and we will help remove it.
12. Your rights (GDPR, UK GDPR, CCPA)
Depending on where you live, you may have the right to access, correct, delete, or restrict processing of your personal information, object to processing, withdraw consent, and not be discriminated against for exercising these rights. California residents may opt out of the sale or sharing of personal information; we do not sell it. Because we do not operate accounts, most data can be removed by deleting the app. For requests, email exostudio.feedback@gmail.com.
13. International transfers
Our providers may process data in countries other than your own, including the United States. They rely on safeguards such as Standard Contractual Clauses.
14. Changes to this policy
We may update this policy. We will change the date above and, for material changes, notify you in the app.
