Simple rules for a private experiment.

Last updated: November 2, 2026 · Private beta

Agreement and eligibility

By using Z4SK you agree to these terms and the Privacy Policy. You must be legally able to use the service where you live. No Filter mode requires both participants to be at least 18 years old.

Your invitation, content and access secrets

You remain responsible for names, questions, answers, links and shared keys you create or submit. You grant Z4SK only the limited right needed to host, transmit, moderate and delete encrypted content while providing the service. A complete invitation link is a bearer secret and can open the invitation. You may add an optional reusable shared key, represented by a branded QR or 12 Spanish BIP39 words; legacy 24-word keys remain valid. When enabled, send it through a different channel and keep both secrets private. The displayed key ID cannot recover or unlock the key. Never publish real secrets in an issue or audit report.

Consent and acceptable use

Use Z4SK only for consensual social interactions. Do not use it for harassment, coercion, threats, stalking, discrimination, impersonation, spam, fraud, sexual exploitation, non-consensual sexual content, illegal activity or collecting credentials, financial data, identity documents or other sensitive information.

Minors

Never sexualize, groom, exploit or solicit intimate content from a minor. Adult-only prompts and No Filter mode must not be sent to minors. Suspected exploitation may be removed and reported where legally required.

Moderation and enforcement

Recipients can report invitations. Rate limits and report thresholds may restrict or close content automatically. Z4SK may remove content, suspend access or preserve limited evidence when reasonably necessary for safety, legal compliance or defending claims.

Temporary access and deletion

Invitations expire after 12, 24, 48 or 72 hours, may be deleted earlier by the creator and may disappear after a single view. You are responsible for saving anything you are entitled to keep before deletion. Provider disaster-recovery history may persist for the period disclosed in the Privacy Policy.

Brand and technology

Z4SK’s software, design, question library, Smart Mix logic, SDK and branding are proprietary unless a third-party notice says otherwise. These terms do not grant permission to copy, resell, reverse engineer or create a competing service from protected materials.

Availability and warranties

The service is provided on an “as available” basis during private beta. Features may change, fail or be withdrawn. To the extent permitted by law, Z4SK disclaims implied warranties and does not guarantee delivery, permanent storage, matches, compatibility or uninterrupted availability.

Liability

Nothing excludes liability that cannot legally be excluded. Otherwise, the operator is not responsible for user content, relationship outcomes, lost links, deleted content, third-party messaging platforms or indirect losses arising from beta use. Final liability caps require review when the operating entity and paid offering are established.

Changes and governing terms

The updated date identifies the current version. If paid features are introduced, their price and any additional applicable terms will be shown before purchase.
