Policy

Terms of use

Last updated: 26 July 2026

Acceptance

By using Silent Key, you agree to these terms, the privacy policy and the community guidelines. Do not use the service if you cannot lawfully agree to them.

Account responsibility

You are responsible for the Google account used to sign in, the devices where the session remains active and activity performed through your Silent Key profile. Do not share authentication access. An SK-ID may be shared as a contact identifier but is not an authentication credential.

Permitted use

Use Silent Key for lawful personal communication. Follow consent, privacy, intellectual-property and safety laws that apply to you. Do not use the service for harassment, exploitation, fraud, malware, credential theft, spam or attempts to bypass security controls.

Temporary messages

Message expiry is a product feature, not a guarantee that content becomes unrecoverable everywhere. Recipients may copy content, cleanup may be delayed and moderation records may retain relevant information. Maintain your own backups of information you need.

Moderation

Silent Key may review reports, remove content, suspend accounts or block accounts to enforce these terms and protect users. The service may preserve information reasonably needed to investigate abuse, security incidents or legal obligations.

Availability

The service is provided on an as-available basis. Features may change, fail or be discontinued. Silent Key does not guarantee uninterrupted delivery, exact presence information, exact-second deletion or recovery of lost content.

No end-to-end encryption promise

Silent Key is a Firebase-backed moderated service and is not represented as end-to-end encrypted. Do not use it when your threat model requires the provider to be unable to access message content.

Account termination

You may request account deletion. Silent Key may restrict or terminate accounts that violate these terms, create security risk or abuse other users.

Changes

These terms may be updated as the service changes. The current version and update date will be published on this page.

Contact

Use the contact form for questions, reports that cannot be submitted in the app, or account requests.
