Privacy Policy for NovaPaper

Last updated: 27 August 2026

This Privacy Policy explains how the NovaPaper mobile application (the “App”, package name app.novapaper.wallpaper) handles your information. NovaPaper is a wallpaper application for Android. We respect your privacy and collect only what we need to run and promote the App.

In short: NovaPaper has no user accounts and does not show ads inside the App. We do not sell your personal information. The App does use three third-party measurement tools — Google Firebase Analytics, the Meta (Facebook) SDK, and the TikTok Business SDK — to understand how the App is used and to measure the performance of our advertising campaigns that run on other platforms.

1. Information We Collect

We do not ask you for your name, email address, phone number, or precise location, and the App has no sign-in. However, the third-party tools listed in Section 3 automatically collect a limited set of technical and usage data, which may include:

• Device and app information — device model, operating-system version, language, country/region, and the App version;
• Usage and event data — app opens, screens viewed, in-app actions (such as setting a wallpaper or completing a purchase), and crash/diagnostic information;
• Identifiers — the Google Advertising ID and app-instance / installation identifiers used to recognise a device across sessions;
• Approximate location — derived only at the country/region level from your IP address. We do not collect GPS or precise location.

We do not collect the contents of your device, your photos, your contacts, or your files. We do not operate our own servers or user database.

2. How We Use This Information

• to measure which of our advertising campaigns lead to installs (attribution), so we do not waste money on ads that do not work;
• to understand which features and wallpaper categories are popular, so we can improve the App;
• to diagnose crashes, performance problems, and bugs;
• to keep track of which content you have unlocked through a purchase.

We do not use this data to build advertising profiles inside the App, and we do not sell it.

3. Third-Party Services

The App includes the following third-party software development kits (SDKs). Each acts as an independent data controller for the data it collects, under its own privacy policy:

• Google Firebase Analytics (Google LLC) — app usage analytics and campaign measurement. See Firebase Privacy and Google’s Privacy Policy.
• Meta (Facebook) SDK — core module (Meta Platforms, Inc.) — app events and install attribution for advertising we run on Meta platforms. See Meta’s Privacy Policy.
  Note: this is the measurement module only. The App does not include the Meta Audience Network and shows no advertisements inside the App.
• TikTok Business SDK (TikTok / ByteDance) — app events and install attribution for advertising we run on TikTok. See TikTok’s Privacy Policy.
  Note: this is the measurement SDK only. The App does not show TikTok advertisements inside the App.
• Google Play Billing (Google LLC) — processes purchases (see Section 6).

4. Advertising ID and Your Choices

The App uses your device’s Advertising ID for the attribution and measurement purposes described above. You control this identifier at the device level:

• Reset or delete it: Android Settings → Privacy → Ads, where you can reset the ID or delete it entirely;
• Opt out of personalisation: the same screen offers “Opt out of Ads Personalisation”. When the Advertising ID is deleted, apps — including this one — receive a string of zeros instead.
• You may also uninstall the App at any time, which stops all further collection.

5. Information Stored Only on Your Device

To make the App work, certain settings and state are saved locally on your device only (using Android’s on-device storage). This information never leaves your device and is not accessible to us. It includes:

• your purchase / unlock status (which wallpaper packs you own);
• your selected theme (System / Light / Dark);
• the wallpaper you last set through the App and any daily-rotation preference;
• a flag indicating you have completed the first-launch welcome screen;
• your purchase history list shown inside the App.

This data is removed if you clear the App’s storage or uninstall the App.

6. Purchases (Google Play Billing)

NovaPaper offers optional one-time in-app purchases (category packs and a Full Access unlock). All payments are processed by Google Play, not by us. We never see or receive your payment card details or billing information. Your purchase is handled entirely by Google under Google’s Privacy Policy. The App only receives confirmation from Google Play that a product was purchased so it can unlock the corresponding content on your device, and so purchases can be restored.

7. Permissions We Request and Why

• Set wallpaper — to apply a wallpaper you choose to your home and/or lock screen.
• Internet — required by Google Play Billing to process purchases, and by the analytics and attribution services described in Section 3.
• Advertising ID — used by the analytics and attribution services in Section 3 to measure advertising performance. See Section 4 for how to reset or delete it.
• Storage (read/write, older Android versions only) — to save a wallpaper image to your device’s gallery when you ask, and to back up your existing wallpaper so it can be restored.
• Run after restart — to re-enable the optional daily wallpaper rotation after your device reboots.

These permissions are used solely for the features described above and only when needed.

8. Children’s Privacy

The App is not directed to children under the age of 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us at the address in Section 10 and we will take steps to delete it.

9. Data Retention and Your Rights

The analytics and attribution data described above is retained by Google and Meta according to their own retention schedules; we do not keep a separate copy. Depending on where you live, you may have the right to access, correct, or delete data relating to you, or to object to its processing.

• To stop collection entirely, delete your Advertising ID (Section 4) or uninstall the App.
• To exercise a data request, contact us using the details in Section 10, or contact Google or Meta directly for data they hold as independent controllers.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last updated” date. Continued use of the App after a change constitutes acceptance of the revised policy.
