Effective 1 July 2026 · Applies to the Sendant mobile app (io.sendant) and web client.
These Terms explain the rules for using Sendant. Please read them together with our Privacy Policy.
Sendant ("we", "us") is the Sendant messenger, developed by Yoni Ryabinski (yoniryabinski.com). You can reach us about these Terms at privacy@sendant.io.
Sendant is intended for adults and is not directed to children under 13. By using Sendant, you represent that you are old enough to use the service under the laws that apply to you and that you can agree to these Terms.
Sendant does not use a phone-number account by default. Your identity is based on cryptographic keys generated and stored on your device. You are responsible for your device, recovery materials, and any activity from your Sendant identity. If you lose access to your device or recovery materials, we may not be able to restore your messages or identity.
You may not use Sendant to:
You are responsible for the messages, attachments, profile labels, and other content you create or send through Sendant. Sendant is designed so our infrastructure cannot read end-to-end encrypted message contents. That means we generally cannot proactively review private message content, but we may act on reports, metadata, abuse signals, legal process, or service-protection needs where we have enough information to do so.
If another user abuses Sendant, use available in-app controls such as blocking where available. You may also contact privacy@sendant.io. Do not include sensitive message content in an email unless you choose to disclose it to us for review.
Sendant is built for end-to-end encrypted, local-first messaging, but no service can guarantee perfect security, anonymity, availability, or delivery. Your device, operating system, app stores, push providers, network providers, and message recipients may affect your privacy and security. People you message can copy, screenshot, or forward content they can see.
Sendant is an early-stage service. Features may change, break, disappear, or be unavailable. We may modify, suspend, or discontinue any part of Sendant, including relay, mailbox, notification, or web-client features.
Sendant is currently offered without in-app purchases, subscriptions, or paid accounts. If paid services are added later, we will provide additional terms before you buy them.
Sendant, its branding, website, app interface, and service components are protected by intellectual-property laws. These Terms do not give you ownership of Sendant or our branding. You keep ownership of content you create, subject to the limited rights needed to transmit, store, deliver, display, and operate that content as part of the service.
Sendant depends on third-party platforms and providers, such as app stores, operating systems, hosting providers, and Firebase Cloud Messaging for Android wake notifications. Their terms and policies may also apply to your use of those services.
You may stop using Sendant at any time. We may limit or terminate access to Sendant if we believe you violated these Terms, created risk for others, or threatened the service's integrity, security, or availability.
Sendant is provided "as is" and "as available." To the maximum extent allowed by law, we disclaim warranties of merchantability, fitness for a particular purpose, non-infringement, uninterrupted operation, perfect security, and guaranteed message delivery.
To the maximum extent allowed by law, we will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost data, lost profits, service interruption, or unauthorized access arising from or related to Sendant.
These Terms are governed by the laws of Pennsylvania, excluding conflict-of-law rules. Venue and dispute terms should be reviewed by counsel before broad launch.
If we change these Terms, we will update the effective date above and, for material changes, surface a notice in the app or on this page. Continuing to use Sendant after changes become effective means you accept the updated Terms.
