Privacy Policy

Call Hole. Last updated: 12 November 2026

Who is responsible

Call Hole ("the app") is made and published by Nicu Glavan, an independent developer, under the name GN33. I am responsible for the app and for this policy. If you have any question about it, write to me at contact.gn33@gmail.com.

In short

The app collects no personal data. It has no ads, no analytics and no accounts, and it has no permission to use the internet. Your rules and the list of calls it screened stay on your phone, and I never see them.

What the app keeps on your phone

To block calls and show you what it did, the app saves a few things in its own storage on your device:

• your rules: the phone numbers and patterns you chose to block or allow, their labels and groups;
• your settings, such as quiet hours, your country and what happens to a blocked call;
• the activity log: for each incoming call the app checked, the caller's number, the time, and whether the call was blocked or allowed and why.

The activity log is kept for 90 days unless you choose another period in Settings, and you can clear it at any time. The app does not send any of this to me or to anyone else. Uninstalling the app, or clearing its data in your phone's settings, deletes all of it.

How the app sees your calls

When you make Call Hole your caller ID and spam app, Android hands it the number of each incoming call from someone who is not in your contacts, and the app answers whether the call may ring. The app does not hear or record calls, and it never sees calls from your contacts. It cannot read your contacts, your call history or your messages, because it does not ask for those permissions.

Android's backup

If you turned on backup in your phone's settings, Android copies your rules and settings to your own Google account, and to a new phone when you set one up, so you do not lose them. That copy is made by Android and Google under Google's privacy policy, and I have no access to it. The activity log is left out of it: who called you and when stays on the phone.

Files you export or share

When you export your rules, the app writes a file to the place you pick. What happens to that file afterwards is up to you. When you share a number from another app to "Block with Call Hole", the app only reads the shared text to fill in a new rule.

What the app does not do

• It has no permission to use the internet, so it cannot send or receive anything.
• It does not show ads and contains no advertising or tracking code.
• It does not use analytics or crash-reporting services of its own.
• It does not ask for an account, an email address or any other contact details.
• It does not access your contacts, location, photos, camera, microphone or files.
• The only permission it asks for is to show notifications, so it can tell you about a blocked call. You can refuse it and the app still blocks calls.

Links

The Website and Privacy policy items in the app's Settings open this website in your phone's browser. Once you are on the website, the app is no longer involved, and the section below applies.

Searching the web for a number

In Activity you can tap the search button next to a call to look up who the number belongs to. The app then hands that one number to the search app on your phone, which runs the search. If your phone has no search app, the app asks your browser to open a Google search for the number instead. This only happens when you tap it, never on its own, and the app itself still does not go online. What the search app, the browser and the search engine do with the number is covered by their own privacy policies, such as Google's.

This website

This website sets no cookies, has no analytics or tracking, and loads nothing from other sites. Like any web server, the company that hosts it keeps short-lived technical logs of requests (such as the IP address, the time and the page asked for) to keep the service running and secure. I do not use these logs to identify anyone.

Google Play

When you download the app from Google Play, Google processes data under its own privacy policy. Google gives me statistics about the app, such as how many people installed it. If you allowed your phone to share usage and diagnostics data with Google, Google may also give me reports of crashes and freezes, which include technical details such as the device model and Android version. These reports do not include your name, your contact details, your rules or the numbers that called you, and I use them only to fix problems in the app.

Children

The app is not aimed at children, and it collects no personal data from anyone, including children.

Your rights

Under data protection laws such as the EU's General Data Protection Regulation (GDPR), you have the right to ask what personal data I hold about you, and to have it corrected or deleted. Through the app I hold no personal data about you, as everything stays on your phone. If you email me, I use your email address and your message only to answer you, and delete them when the conversation is over. You can also complain to the data protection authority in your country.

Changes to this policy

If the app changes in a way that affects your privacy, I will update this page before that version of the app is released, and change the date at the top.
