Privacy Policy

Audio processing and local settings

• When you activate Volume Guard, the extension captures the audio stream of the selected tab solely to provide local volume normalization and output control.
• Tab audio is processed inside the browser. Volume Guard does not record, store, upload, sell, or share the audio.
• Presets, output volume, Night Mode, site exclusions and settings, language, account state, and the entitlement cache may be stored in Chrome local storage.

Account, authentication, purchase, and subscription data

• Email OTP sign-in processes your email address, a random installation-scoped device ID, authentication request and session state, and token hashes.
• The refresh token used to keep you signed in is stored in Chrome local storage restricted to extension contexts. Only token hashes are stored by the backend.
• IP addresses may be processed for authentication security and abuse-prevention rate limiting. They are not used for advertising, profiling, or location tracking.
• The Volume Guard backend stores the minimum records needed to operate accounts and verify Pro access. For one-time purchases, account-linked records may include the provider, order, store, product, and variant identifiers; a Test/Live marker; purchase status; total and refunded amounts; and purchase, refund, provider-update, and record timestamps. Email-account records, device and session metadata, subscription identifiers, status and period dates, and webhook-processing records may also be stored.
• The backend uses PostgreSQL for these records, Resend to send authentication email, and encrypted AWS S3 backups. These providers process data only to deliver the relevant service.

Payments

Lemon Squeezy is the merchant of record for Volume Guard Pro and handles checkout, payment processing, taxes, and receipts. To verify Pro access and process refunds, Volume Guard may store the limited purchase metadata described above. It does not store raw payment credentials such as full card numbers or CVV.

Diagnostics and tracking

Support reports and diagnostics are not transmitted automatically. You review the in-app form and they are sent only when you press Submit report. You may submit anonymously or associate a report with your account when a valid sign-in session is used.

An in-app report stores the category, title, description, optional reproduction steps, extension version, language, report status, opaque public report ID, and timestamps. Diagnostics are optional and limited to a strict whitelist of extension and manifest version, browser summary and language, UI language, active state, current gain, input level, output volume, normalization strength, Night Mode state, scope, and plan. The current site hostname is a separate opt-in.

Support reports do not include raw audio, full URLs, page titles, saved-site hostname lists, access or refresh tokens, OTPs, device/session secrets, email or client-supplied user IDs, Lemon Squeezy customer or subscription IDs, checkout/order/payment data, or arbitrary Chrome storage.

Support operations and abuse prevention

Operators can access recent reports and change report status through private backend tooling. The support endpoint may process the request IP address for abuse prevention. The current MVP limiter is process-local, resets on backend restart, and is not shared across multiple instances.

Retention and deletion

• Signing out removes local authentication data and the entitlement cache. Other local settings are removed when you uninstall the extension or clear its Chrome storage.
• Support reports are retained for a default period of 180 days and then deleted by the backend retention cleanup. Encrypted backup copies expire through a separate rolling retention cycle and may remain until that cycle completes.
• For access or deletion requests, contact the support email below. Do not post personal data in a public issue.
• Transaction records held by Lemon Squeezy follow its retention requirements and applicable law.

Chrome Web Store Limited Use

Information received from Chrome extension APIs is used only to provide Volume Guard's user-facing features and is handled in accordance with the Chrome Web Store User Data Policy, including its Limited Use requirements.

Terms of Service

• Volume Guard helps normalize web-tab audio and reduce sudden loud sounds, but it cannot guarantee identical perceived loudness for all content.
• Core normalization and safety features are provided on Free. New Pro purchases are one-time purchases with no subscription or recurring charge and unlock the Pro features shown in the extension, including Advanced Mixer. Existing subscription accounts remain supported for their current status and management.
• You must have the right to access the content and accounts you use and must follow applicable law and site terms.
• Features or service terms may change for reliability, security, or legal requirements. Material changes will be communicated through the extension or support channel.
• The service is provided as available and does not guarantee operation on every website, audio source, or device.

Pro Purchases and Legacy Subscriptions

• New Pro purchases are one-time purchases with no subscription or recurring charge. Before payment, the Lemon Squeezy checkout shows the product, price, currency, and taxes.
• Existing legacy subscribers can review or cancel their subscription through Manage subscription under the terms of their existing plan. An uncanceled legacy subscription renews according to those terms.
• Canceling a legacy subscription leaves Pro available through the current paid period, then changes access to Free after the period ends and entitlement synchronization completes.
• If access from a purchase or legacy subscription is delayed, use Refresh access in the extension.

Refunds

• Submit refund requests through the Lemon Squeezy seller-support path shown on your purchase receipt. Eligibility is reviewed under applicable law and the terms disclosed at purchase.
• Canceling a legacy subscription stops its next automatic renewal but does not automatically refund a period that has already been paid.
• For a duplicate or unauthorized charge, or a suspected failure to provide the service, contact the Lemon Squeezy seller-support path with your receipt.

Support and Contact

Use the in-app report form as the primary support path. If the service is unavailable, create a public support request on GitHub as a fallback, or contact support privately by email for account, access, or deletion requests.

Do not post your email address, OTP, authentication tokens, order, customer, or subscription IDs, or other personal data in a public issue. Use email for account, privacy-access, or deletion requests. For billing and refund questions, first use the Lemon Squeezy seller-support path shown on your receipt.
