Your privacy matters.

Last updated: September 24, 2026. This policy describes the current LockChime application operated by the independent LockChime project. Contact us through the contact form for privacy requests.

Audio conversion stays on your device.

The converter decodes, trims, and exports your audio locally in your browser. It does not upload your source file to our server or an AI provider. Closing or reloading the page clears the audio held in memory.

Preferences and essential storage.

Your theme and saved-sound identifiers are stored in your browser’s local storage. They are not synchronized to an account. An unfinished AI prompt is kept in tab-scoped session storage so it survives a refresh; closing the tab clears it. Signing in creates an essential, HTTP-only session cookie. You can clear local preferences in your browser or sign out to end your session.

Accounts and private AI generations.

If you use the AI studio, we store your verified email, account identifier, generation prompts, request status, quota usage, estimated provider charges, and output files. Email sign-in uses Resend when configured. Human verification uses Cloudflare Turnstile. Prompts are sent to fal and the selected Sonilo model to create the requested audio; we do not send your email as part of the generation prompt.

Private audio is available for seven days, then our background worker deletes the local output and clears the prompt. You can delete completed results sooner. Deleting your account removes your email, sessions, and stored private outputs once active jobs finish. Minimal pseudonymous accounting records may remain for cost reconciliation. The AI provider may retain data separately under its own terms; local deletion does not guarantee immediate provider-side deletion.

Usage counts and technical records.

The server counts audio delivery responses by sound and day. This does not prove a file was saved, played in a car, or copied to USB. Optional first-party usage events such as previews and converter exports are off until you allow them in Privacy choices. They store aggregate daily counts, without a cross-site advertising identifier. Do Not Track and supported Global Privacy Control signals disable optional event collection.

For abuse prevention, the app may temporarily keep hashed network identifiers and request counters. Your hosting provider may independently retain access logs. Contact messages and any optional vehicle details are stored for support review; please avoid sensitive information.

Advertising and your choices.

Google AdSense is loaded only when enabled and after the configured consent mechanism allows it. In supported regions, Google’s certified consent message manages advertising choices. Refusing advertising consent or blocking advertisements does not stop downloads or conversion. Our separate Privacy choices control optional first-party statistics, not Google advertising consent.

Your rights and contact.

Depending on your location, you may have rights to access, correct, delete, or restrict use of personal information. Use account deletion in the studio or send a privacy request. We will ask for enough information to verify that the request is yours. The AI studio is intended for adults; the public tools do not require an account.
