Effective and last updated August 23, 2026. These terms cover the Volume Lock Android app and optional Premium purchase options.
These Terms of Use apply to the Volume Lock Android app developed and operated by Alexander Aizendorf as an individual developer. By downloading, installing, purchasing through, or using Volume Lock, you agree to these terms. If you do not agree, do not use the app.
You may use Volume Lock for personal use on devices where it is installed through an authorized app store. You may not copy, modify, redistribute, sell, sublicense, reverse engineer, extract source code from, translate, or create derivative works from the app, except where applicable law gives you a non-waivable right to do so.
Trademarks, copyrights, database rights, and other intellectual property rights related to Volume Lock remain the property of their respective owners.
Volume Lock can be used without a Premium purchase, and its core functionality remains available without Premium. The Free app is supported by advertising. Google Play may offer Volume Lock Premium as an annual auto-renewing subscription or as a separate Lifetime one-time purchase. Premium currently removes banner and fullscreen ad requests while verified Premium access is active. Firebase Analytics remains enabled under the applicable privacy and consent rules.
Before purchase, Google Play displays the current localized price, currency, applicable taxes, eligibility, and final commercial terms. For Annual, Google Play also displays the billing period and renewal terms. The terms shown by Google Play control the transaction. Annual renews automatically for another annual period unless it is canceled before renewal. Lifetime is a one-time purchase with no recurring charge.
Price changes follow Google Play's notice, consent, and effective-date procedures. Volume Lock does not promise a specific global price or unspecified future Premium features.
Google Play may make a seven-day free trial available to an eligible user. Eligibility is determined by Google Play and is not guaranteed. When offered, the trial automatically converts to the paid annual subscription at the localized annual price shown by Google Play unless you cancel before the trial ends.
If Google Play does not return the trial offer or you are not eligible, Volume Lock makes no trial claim and offers the localized annual purchase path directly. Volume Lock remains usable without starting a trial.
Manage or cancel Premium through Google Play subscriptions. If the specific page is unavailable, use the general Google Play Subscription Center. Uninstalling or clearing Volume Lock data does not cancel a subscription.
An ordinary cancellation stops future renewal. Premium normally remains available until the end of the verified paid period, subject to Google Play state, refund or revocation, and applicable law.
Google Play is the purchase authority. A Billing response alone does not grant Premium. After Google Play reports a completed purchase, Volume Lock sends the purchase token to its entitlement service. Premium is granted only after server verification succeeds against the Google Play Developer API. A pending purchase is not acknowledged and does not grant Premium.
A signed entitlement credential may preserve bounded offline access. It cannot extend access beyond its limits or the latest verified Google Play state. Restore starts from completed purchases returned for the current Google Play account and performs the same server verification. Volume Lock has no separate app account.
You may contact Google Play or Volume Lock support regarding a cancellation or refund. Subscription billing and cancellation are processed through Google Play. All approved refunds are processed through Google Play. Volume Lock does not promise discretionary developer refunds. Where applicable law or a Google support process requires developer action, Volume Lock uses Google Play Console or the Google Play Developer API.
A refund or revocation may end Premium before the originally scheduled expiry. A failed renewal may produce a grace period, account hold, or expiry according to Google's verified subscription state. Mandatory consumer rights and remedies are not excluded.
Volume Lock uses Google Play services, Google Play Billing, AdMob, Google's User Messaging Platform, Firebase Analytics, Cloudflare subscription infrastructure, and related provider services. Their terms and privacy policies may also apply. See the Privacy Policy for details about processing and providers.
You are responsible for keeping your device secure and maintaining access to the app and Google Play account used for a purchase. Rooting, jailbreaking, or bypassing operating-system protections may affect security and may cause Volume Lock or purchase verification to work incorrectly.
Some features require an internet connection. Your network provider may charge for data usage or roaming. You are responsible for those charges and for having permission from the bill payer where applicable.
Volume Lock is provided as is to the extent permitted by law. App, device, network, Google Play, or entitlement-service interruptions may occur. The developer works to keep verification, restore, management, and support available but cannot guarantee uninterrupted service or compatibility with every device and Android version.
Nothing in these terms excludes mandatory consumer rights, statutory warranties, liability, or remedies that cannot lawfully be excluded or limited.
Volume Lock may update or change the Free app and may stop new Premium sales. For existing subscribers, Volume Lock will continue to provide Premium's core ad-suppression benefit through the verified paid period unless Google Play reports a refund, revocation, expiry, or other state that ends access. Stopping new sales does not disable verification, restore, subscription management, or support for existing subscribers.
If Volume Lock permanently discontinues Premium or a developer-side failure prevents it from providing the paid benefit, Volume Lock will restore access or provide an appropriate refund through Google Play.
You may need to install app updates to continue using some features. Premium access may be suspended only when reasonably necessary to address verified fraud, chargeback, entitlement abuse, a security threat, a legal requirement, or a material breach of these terms. Any suspension remains subject to existing paid-period obligations, mandatory rights, and Google Play processes.
If the Free app or a Free feature is discontinued, the related rights granted under these terms end as applicable. Existing Premium obligations remain governed by section 12.
These terms may be updated when the app, Premium service, providers, legal requirements, or operating practices change. Updated terms will be posted on this page with a revised date. Material subscription changes remain subject to Google Play procedures and applicable law.
Authoritative language: English.
Premium Lifetime is a single, non-recurring purchase and does not automatically renew. It grants the Google Play account that owns the purchase access to the Premium benefit included in Volume Lock—currently the removal of banner and fullscreen advertising requests—for the Supported Life of Volume Lock.
“Supported Life of Volume Lock” means the period during which the developer continues to publish, maintain, or otherwise make Volume Lock, or a substantially equivalent successor product, available. Stopping new Lifetime sales, renaming or updating the app, transferring the app, or replacing it with a substantially equivalent successor does not by itself end an existing verified Lifetime entitlement. The product may be permanently discontinued for legitimate legal, security, technical, or commercial reasons, but not solely to avoid existing Lifetime obligations.
“Lifetime” does not mean the lifetime of the purchaser or any device and does not guarantee compatibility with every future device, Android version, app store, API, network, or third-party service. New products or separately priced features are not included unless expressly stated.
Purchase, restore, and periodic verification normally require the Google Play account that owns the purchase, a compatible installation, network access, and availability of the applicable Google Play services. Temporary verification or restore outages do not terminate a verified Lifetime entitlement. App-store removal or account suspension may prevent new downloads or restoration, but does not by itself cancel an existing entitlement or any mandatory consumer remedy.
Google Play remains the purchase authority. A pending Lifetime purchase does not grant access. A completed purchase grants access only after server verification. Same-account restore after reinstall or on a second compatible device begins with the completed purchase returned by the Google Play account that owns it and repeats server verification.
Refund, revocation, and chargeback outcomes follow authoritative Google Play state and may end Lifetime access. If the authoritative state later permits a new purchase, any repurchase uses the then-current Google Play offer and verification flow. Support does not override the authoritative state.
If permanent discontinuation materially prevents delivery of the purchased benefit, the developer will use reasonable efforts to restore access, migrate the entitlement to a substantially equivalent successor, or provide an equivalent alternative. If that is not reasonably possible, the purchaser remains entitled to the remedies required by applicable law, which may include a price reduction or refund. Google Play policies and payment channels may govern processing where available, but they do not exclude mandatory consumer rights.
The contracting party and developer is Alexander Aizendorf, acting as an individual developer operating Volume Lock.
