Last updated July 16, 2026. This page covers the Volume Lock Pro Android app.
This Privacy Policy applies to the Volume Lock Pro Android app developed by Alexander Aizendorf. It explains how the app handles information directly and how third-party services may process information when the app is installed, purchased, licensed, or used.
Volume Lock Pro does not require you to create an account with us. The app does not ask for your name, postal address, phone number, contacts, precise location, photos, microphone, camera, SMS messages, or call log. The app does not provide a public posting or user-generated content feature.
Volume Lock Pro helps keep selected Android volume streams at the values or ranges you choose. The app stores its core settings locally on your device, including:
The developer does not operate a server that receives your saved volume rules or local app preferences. Android backup or device-transfer features may copy selected app preferences through your Google or device backup settings.
The app requests Android permissions only for app functionality. Depending on your device and Android version, these permissions may include access to modify audio settings, show notifications, run a foreground service, restart protection after boot, observe network availability, schedule exact alarms, open vendor auto-start settings, and request access to Do Not Disturb controls. The app uses these permissions to keep volume protection reliable and does not use them to collect contact, message, photo, camera, microphone, or precise location data.
Volume Lock Pro is distributed as a paid app through Google Play. Google Play handles the purchase, payment method, taxes, refund processing, and related transaction records under Google's terms and privacy policy. Volume Lock Pro does not receive your payment-card or bank details, Google email address, order ID, price, or transaction receipt through the license-check flow.
To confirm that the installed copy is licensed and has not been tampered with, Volume Lock Pro uses Google Play Integrity and the Volume Lock license service hosted on Cloudflare. A license request processes the app package name, version code, a random locally generated install ID, a five-minute server challenge, a request hash, a Google Play integrity token, timestamps, and the resulting license decision. Google Play Integrity processes the signed-in account's app licensing status together with app-integrity and device-integrity information for this security check.
The license service also processes IP address, ASN, and country metadata for abuse prevention and bounded rate limiting. It derives an HMAC-derived server-side key from the random install ID instead of using the raw install ID as its server-side session name. License traffic is encrypted in transit.
Volume Lock Pro does not use AdMob and does not display ads. Firebase Analytics is packaged and enabled to understand app usage and improve the product. Firebase Analytics automatically processes an app-instance identifier, the Android advertising identifier where available, a masked IP address, IP-derived approximate location, device and operating-system information, screen views, sessions, and other app lifecycle interactions. Volume Lock Pro does not request Android precise- or approximate-location permission and does not collect GPS location.
Firebase Analytics data is encrypted in transit. Google retains and processes Analytics data under the configured Firebase and Google Analytics controls and policies.
If you contact support by email, we receive the information you choose to send, such as your email address, message, screenshots, device details, and optional debug logs. Support information is used to answer your request, diagnose issues, and improve the app.
The app relies on third-party services that operate under their own privacy terms:
We do not sell personal information. Information is processed by Google for distribution, licensing, Play Integrity, and Firebase Analytics, and by Cloudflare for the Volume Lock license service, security controls, and operational logs. Information may also be disclosed when required by law, to respond to a valid legal request, protect rights or safety, investigate abuse, or resolve a licensing or support dispute.
Local app settings and the random install ID remain on your device until you change them, clear app data, remove applicable Android backup data, or uninstall the app. License challenges are valid for five minutes. Per-install session rate-limit timestamps are retained for fifteen minutes and are pruned during later session processing. The outer Cloudflare abuse control uses a sixty-second rate window. Cloudflare Workers logs are retained for up to seven days under the deployed plan.
Support messages and attachments are retained for up to 24 months after the support case closes. A documented legal, security, fraud, chargeback, refund, or unresolved-support hold may preserve only the records required for that purpose until the hold is reviewed and released. Firebase, Google Play, Play Integrity, Cloudflare, Android backup, and the email provider may retain information under their own configured controls and policies.
You can clear app data, uninstall Volume Lock Pro, and manage Android backup data through your device and Google settings. You may request deletion of support communications or other information Volume Lock reasonably controls by emailing volumelockkapp@gmail.com. Because Volume Lock Pro has no developer account, support may request limited non-public evidence needed to locate a licensing or support record. Limited records may be retained where required for security, fraud prevention, legal compliance, an unresolved dispute, or a documented hold.
Volume Lock Pro is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through a support request or another channel, contact us so we can take appropriate action.
Volume Lock Pro uses encrypted network transport, bounded and single-use license challenges, request hashing, Google Play Integrity verification, an HMAC-derived server-side install key, access controls, and sanitized operational logging. No app, device, or internet service can guarantee absolute security.
This policy may be updated from time to time. Changes will be posted on this page with a new last updated date. Continued use of the app after a policy update means the updated policy applies to your use of the app.
Questions about this policy can be sent to support.
