Note
In short. Block Checker needs no account and does not know who you are. The domains you check are sent to our server only to look them up, and anonymous statistics help us keep the app working.
About this policy
This policy explains how Block Checker (iPhone, iPad and Android) handles your data. The app is developed by ONLYAPPS d.o.o., Futoška 1A, 21000 Novi Sad, Serbia (registration number 21858277), the controller of any personal data described here. Contact: privacy@onlyapps.org.
The app does not require registration and never asks for your name, email or phone number.
What the app collects
| Data | What exactly | Why | Linked to you |
|---|---|---|---|
| Domains you check | The domain name you enter | To look it up in our directories and run the DNS check | No |
| Usage data | Screens opened, features used, app version | To understand which features are useful and improve the app | No |
| Diagnostics | Crash reports, performance data, device model and OS version | To find and fix errors | No |
What we never collect
- Your name, email or phone number
- Your location
- Contacts, photos or files on your device
- Any history of your checks linked to you
Third-party services
- Firebase (Google LLC) — anonymous usage statistics and crash reports. Firebase privacy
- AppMetrica (Yandex) — anonymous usage statistics and crash reports.
- Apple App Store and Google Play — app distribution.
These services process data under their own privacy policies and may do so outside Serbia. We do not sell data and do not use it for advertising.
How long we keep data
Domain lookups are processed to return the result and are not stored together with any identifier. We do not keep personal data about you on our servers. Anonymous usage statistics and crash reports are stored by Firebase and AppMetrica for a limited period according to their settings (typically up to 14 months) and are then deleted.
Your rights
Under the Serbian Law on Personal Data Protection and, where it applies, the EU GDPR, you can ask us for access to, correction or deletion of your data, object to its processing, or withdraw consent. Because the app does not know who you are, the data we receive is not linked to you and we usually cannot single out your records — but we will always answer your request at privacy@onlyapps.org within 30 days. You can stop all data collection at any time by deleting the app, and you can limit analytics in your device privacy settings. You may also lodge a complaint with the Commissioner for Information of Public Importance and Personal Data Protection of the Republic of Serbia (poverenik.rs).
Children
Block Checker is not directed at children under 15, and we do not knowingly collect personal data from children.
Changes to this policy
We may update this policy when the app or the law changes. The current version and its effective date are shown at the top of this page; earlier versions remain available in the document history.
