Ad ID Viewer — Privacy Policy

Last updated: 2026-10-07

This policy is written in English. It describes how Ad ID Viewer handles information.

Who we are

Ad ID Viewer (com.devttl.adid) is an Android utility that shows the Google Advertising ID (GAID) available through Google Play services.

The developer is DevTTL (开发生存时间). DevTTL does not operate an account system or a server that receives your advertising ID.

Questions about this policy: [email protected].

Information accessed on the device

The app reads the following on your device so it can show them to you:

DevTTL does not write the advertising ID into the app’s own files, and does not send it to a DevTTL server. Android backup is enabled for the app, but the app does not save the advertising ID in its own storage.

The app does not ask you to create an account. It does not collect your name, email address, contacts, photos, precise location, or payment information.

Copy and share

Copy and share run only when you tap those actions.

Advertising and Google

The app shows a banner ad through the Google Mobile Ads SDK (Google AdMob).

The app also uses Google Analytics for Firebase (Firebase Analytics) to understand how the app is used. Collection starts automatically. The app does not log the advertising ID shown on screen as an analytics event.

Firebase Analytics may collect:

DevTTL does not sell your advertising ID. DevTTL does not operate a server that receives the advertising ID shown in the app. Google processes advertising and analytics information. DevTTL can view analytics in the Firebase and Google Analytics consoles. That processing is covered by Google’s Privacy Policy and Firebase privacy and security.

The app does not show its own consent dialog. You can limit or reset the advertising ID in your device settings, and you can review Google ad controls at adssettings.google.com.

What we do not do

Google’s advertising and analytics services may still collect and share data as described above. That processing is handled by Google, under Google’s policies.

Permissions

Retention

DevTTL does not keep a copy of your advertising ID in the app’s own files. Text you copy remains on the clipboard until the system or another app replaces it. Text you share is handled by the app you select.

Analytics data is retained according to the retention settings of this app’s Firebase project and Google’s policies. Information processed by Google for advertising is retained according to Google’s policies. You can email [email protected] to ask about analytics data for this app. To ask Google about advertising data, use the controls and contact options Google provides.

Security

The advertising ID is read on the device and shown in the app. Transmission of ad requests and analytics events is handled by Google’s SDKs. No method of transmission or storage is perfectly secure.

Children

Ad ID Viewer is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through this app, contact [email protected].

Your choices and regional rights

You may contact [email protected] to ask what information DevTTL holds about you, including analytics data for this app, or to ask that it be deleted where Google’s tools allow. DevTTL does not store the advertising ID in the app’s own files. You can also reset or delete the advertising ID in Android settings.

If you are in the EEA or the United Kingdom, you may request access, correction, or deletion of personal information that DevTTL holds, and you may object to or restrict certain processing. Send the request to [email protected]. Advertising and analytics processing by Google are described in Google’s Privacy Policy.

DevTTL does not sell personal information. If a US state privacy law gives you a right to opt out of the sale or sharing of personal information, that opt-out for DevTTL’s own practices is already reflected here: we do not sell it. Advertising by Google is controlled through your device advertising-ID settings and Google ad settings.

Changes

We may update this policy when the app’s features or data practices change. The date at the top of this page is the date of the latest version. Continued use of the app after an update means you accept the revised policy.
