To renew your license, you do not need to reinstall or stop the application. Just purchase a new license in the app.

To purchase a license

1. Open Menu in the top-right corner of the app main screen and choose License. On the License screen, tap Purchase new license.

2. You will be redirected to the Doctor Web online store.

   You can also open the online store at https://estore.drweb.com/family_security/.

3. Select the license period and the number of devices to protect, then tap Buy.

4. Fill out the form and select Continue.

   After you complete your purchase, you will be sent a serial number. You can choose to receive the serial number via email or SMS message. You will also get an email with the license key file. You can use it to activate or restore your license (see below).

5. Return to the application. On the License screen, select Enter serial number.
6. Enter your purchased serial number and tap the Activate button.

If the license is not activated because of a possible technical issue, contact our technical support: https://support.drweb.com/.

Instead of a serial number, you can also use a key file. On devices with Android 11.0 or later, you will have to grant the Access to all files permission.

To use a key file

1. Copy the key file to your device to a folder in the internal memory. Either you can copy the entire ZIP archive, or you can unpack the archive and copy only the .key file to your device.
2. On the License screen, select Use key file.
3. Open the folder where you have copied the key file or the entire ZIP archive to, and tap it. The key file will be installed and ready to use. You will be redirected to the Family Security main screen. At the bottom of the screen, you will see a notification about a successful license activation.
