Terms of Service

Effective Date: September 8, 2026

These terms are a legal agreement between you and Korrelated, LLC (“Korrelated,” “we,” “us”) covering the Kontaks apps for iPhone and Android and the kontaks.io website, together the “Service.” By using the Service you agree to them. If you do not agree, do not use the Service.

1. Eligibility — adults only

You must be at least 18 years old to use Kontaks. There is no younger tier, no parental-consent path and no supervised mode. If you are under 18, you may not use the Service, and we will remove access from any use we become aware of.

You must also be legally able to enter into this agreement, and you must not be barred from using the Service under the laws of your jurisdiction.

2. There is no account, and what that means for you

Kontaks has no username, no password, no email address and no phone number. Your identity in the Service is a set of cryptographic keys generated on your own devices. We cannot recover them, reset them, or transfer them to another person, and no support request can make us able to.

You are responsible for your devices and for the recovery method you chose, if you chose one. If you lose every device on your keyring and have no backup, your contacts cannot be recovered by us or by anyone else. This is a consequence of the design and is not a defect.

Because there is no account, the way to remove everything we hold is the “delete everything” purge in the app, which acts across every device on your keyring. See deleting your data.

3. Your content, and the licence you give us

Everything you send through Kontaks — messages, voice messages, call audio, avatars, names you present, group names and notes — is yours. You keep every right in it.

You grant us the narrow, non-exclusive licence we need to operate the Service: to store and transmit your content in encrypted form for as long as it takes to deliver it, and no longer than seven days. That licence covers nothing else. It does not permit us to read, analyse, publish, train on, or share your content, and in the ordinary case we could not do any of those things if we wanted to, because the content is encrypted end to end and the keys never reach us.

4. Acceptable use — zero tolerance for objectionable content and abusive behaviour

There is zero tolerance for objectionable content or abusive behaviour on Kontaks. You agree not to use the Service to:

  • send, request, or solicit sexual content involving a minor, or any material that sexually exploits or endangers a child, in any form;
  • harass, threaten, stalk, defame, or intimidate any person, or incite anyone else to;
  • send content that promotes violence, terrorism, or self-harm, or that promotes hatred against people on the basis of race, ethnicity, national origin, religion, disability, sex, gender identity, sexual orientation, age, or veteran status;
  • send unsolicited commercial messages, chain messages, scams, phishing, or fraudulent offers;
  • impersonate another person in a way intended to deceive;
  • infringe anyone's copyright, trademark, or other rights;
  • break the law, or help someone else break it;
  • attempt to defeat, reverse engineer, or interfere with the Service's security, rate limits, or pairing system, or to enumerate invite tokens or routes;
  • use the Service to build a competing dataset, or automate access to it outside a use we have agreed to in writing.

We cannot read your messages, so we cannot police them. This section is enforced in the three ways that are actually available to us, and we would rather say that plainly than imply a moderation capability we do not have:

  1. You can end any contact, immediately and permanently. Deleting someone destroys the line in both directions. It is unilateral, takes effect at once, requires nobody's agreement and cannot be undone or appealed by them. This is the primary remedy and it is stronger than anything a moderation team could offer you.
  2. You can report without us reading anything. A report carries what you choose to include. We act on the account-level signal, not on the content of your conversation.
  3. We can remove access to the Service from a device or a set of devices, and we will, where we have credible grounds to believe this section has been breached — particularly where a child has been endangered.

We may act on reports, on abuse signals visible at the infrastructure level, and on lawful requests. We are not obliged to act on any particular report, and we do not undertake to monitor the Service.

5. Copyright and the DMCA

We respect copyright. Because we cannot read content, a takedown notice naming a message we cannot see has nothing we can act on directly; what we can do is act against the access of a repeat infringer we can identify from the notice. Send notices to legal@kontaks.io with the elements required by 17 U.S.C. § 512(c)(3).

6. Subscriptions and payment

Kontaks has a free tier and paid plans. All billing is handled by Apple and Google, through your App Store or Google Play account. We do not take your payment details and we never see them.

  • Subscriptions renew automatically until you cancel them, in the App Store or Google Play.
  • Refunds are Apple's and Google's to give. We cannot issue one, reverse a charge, or see your billing history.
  • Deleting your data does not cancel a subscription. You must cancel it separately with the store you bought it from, or you will continue to be charged.
  • We may change prices and plan limits. Changes apply from your next renewal, and we will give notice in the app before they take effect.

7. What the Service is not

Kontaks is not a telephone service

You cannot call 911 or any other emergency number from Kontaks. It has no carrier connection, no location delivery to an emergency dispatcher, and no route to one. Keep your regular phone service for emergencies. Kontaks also needs an internet connection: there is no SMS fallback, because an SMS fallback would require a phone number.

Kontaks is not a records system, an archive, or a backup service. Our servers hold undelivered content for at most seven days and then discard it, whether or not it was delivered. The only durable copy of your conversations is on your own devices, and keeping them is your responsibility.

8. Availability and changes to the Service

We may change, suspend, or discontinue any part of the Service. We will give reasonable notice in the app of a change that materially reduces what you get, and if we discontinue the Service entirely we will give notice with enough time to export what you want to keep from your own devices.

9. Intellectual property

The Kontaks apps, this website, the name, the logo and everything else we made remain ours. These terms give you a personal, revocable, non-transferable, non-exclusive licence to use the app on devices you own or control, for your own non-commercial and internal business purposes, and nothing more.

10. Third-party services

Kontaks relies on Apple and Google for app distribution, billing and push notification delivery, and on infrastructure providers for hosting and call relaying. Their terms apply to their part of the arrangement. Push notifications necessarily pass through Apple's and Google's systems; the payloads carry an opaque route identifier and ciphertext, and nothing else.

11. Content is other people's, not ours

Everything you receive on Kontaks comes from a person you explicitly authorized to reach you. We do not create, endorse, verify, or vouch for any of it, and we have no way to. If someone abuses the access you gave them, delete them: the line ends in both directions, immediately.

12. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT MESSAGES OR CALLS WILL BE DELIVERED.

We describe our security design in detail on the security page, including what it does not defend against. Describing what we built is not a guarantee of any outcome, and nothing on that page or anywhere else is one. Kontaks has not been independently audited.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KORRELATED WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, CONTACTS, MESSAGES, PROFITS, OR GOODWILL, ARISING OUT OF OR RELATING TO THE SERVICE. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE, OR (B) FIFTY US DOLLARS.

Some jurisdictions do not allow these limits, in which case they apply to the fullest extent that jurisdiction permits.

14. Indemnification

You agree to indemnify and hold harmless Korrelated, LLC and its members, officers and agents from any claim, damage, loss or expense (including reasonable legal fees) arising out of your use of the Service, your content, or your breach of these terms.

15. Dispute resolution

We would rather fix a problem than argue about it — write to support@kontaks.io first, and give us thirty days to resolve it.

If that fails, you and Korrelated agree that any dispute arising out of or relating to these terms or the Service will be resolved by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, in the county where you live or another mutually agreed location, rather than in court. You and we each waive the right to a jury trial and to participate in a class action. Either of us may bring an individual claim in small-claims court instead. Nothing here prevents either of us from seeking injunctive relief for infringement or misuse of intellectual property.

You may opt out of this arbitration agreement by writing to legal@kontaks.io within 30 days of first accepting these terms. Opting out affects nothing else in this agreement.

16. Governing law

These terms are governed by the laws of the State of Delaware, without regard to its conflict-of-laws rules, except that the Federal Arbitration Act governs section 15.

17. Termination

You may stop using Kontaks at any time, and you may remove everything we hold with “delete everything” in the app. We may remove your access to the Service if you breach these terms, particularly section 4. Sections 9 and 12 to 16 survive termination.

If we remove your access, your contacts are told nothing. Their messages to you simply fail, exactly as they would if you had deleted them yourself.

18. Changes to these terms

If we change these terms, the updated version will be indicated by the Effective Date at the top of this page. If the change is material we will also give notice in the app before it takes effect. Continuing to use the Service after that is acceptance.

19. Severability and entire agreement

If any provision is held unenforceable, the rest stays in force. These terms and the Privacy Policy are the entire agreement between you and Korrelated about the Service, and supersede anything said before.
