SYNC Terms of Use

Version 2026-09-25 · effective 25 September 2026

These Terms of Use (the “Terms”) are the agreement between you and AXIOMIC LTD about your use of the SYNC app and service (“SYNC”).

By creating a SYNC account or using SYNC you accept these Terms and confirm that you have read the Privacy Policy. If you do not agree, do not use SYNC.

1. Who provides SYNC

SYNC is provided by AXIOMIC LTD, a company registered in the Republic of Cyprus under number HE 480260, with its registered office at Charalampou Mouskou & Grigori Afxentiou 20, Athinodorou Business Center, Floor 3, Office 306, 8010 Paphos, Cyprus (“we”, “us”).

Contact: [email protected].

2. Who can use SYNC

• You must be at least 16 years old. SYNC is not meant for anyone younger, and we close accounts that we learn belong to someone under 16.
• You must be able to enter into a binding contract, and the law that applies to you (including sanctions law) must not bar you from using SYNC.
• One account per person. Use an email address that is yours and a name that does not pretend to be someone else.
• Keep your password to yourself. You are responsible for what is done with your account; tell us at once if you think someone else has used it.

3. What SYNC is

SYNC is a messenger: one-to-one and group chats, voice messages, photos, videos, files, and voice and video calls. People on SYNC can find you by your name, or by your exact email address, and add you as a contact; contacts and members of the same group can message and call you.

SYNC is free. It has no in-app purchases and no advertising.

Messages and calls are encrypted in transit between your device and our servers, but SYNC is not end-to-end encrypted. The Privacy Policy explains what this means.

SYNC is not a telephone service and cannot be used to call emergency services.

We may change, add or remove features. We work to keep SYNC available, but we do not promise that it will always be available, uninterrupted or free of errors, or that every message or call will be delivered.

4. Zero tolerance for objectionable content and abusive users

SYNC has zero tolerance for objectionable content and abusive users. You must not use SYNC to create, send, share or store any of the following, or add people to chats to spread it:

• content that sexually exploits or endangers children, including any sexual content involving a minor;
• sexual content sent to someone who did not ask for it, and intimate images of anyone shared without their consent;
• harassment, bullying, stalking, threats or intimidation, or encouraging violence against anyone;
• hate speech: content that attacks or demeans people because of race, ethnic or national origin, religion, disability, sex, gender identity, sexual orientation, age or a similar characteristic;
• content that promotes terrorism or violent extremism, or violence shown to shock or to glorify it;
• content that encourages suicide, self-harm or eating disorders;
• other people’s private information — addresses, phone numbers, identity documents, private photos — shared without their permission;
• spam, chain messages, bulk or automated messages, scams, phishing, or links to malware;
• impersonation of a person or an organisation, or misleading others about who you are;
• offers or sales of illegal goods or services, such as drugs, weapons or stolen data;
• content that infringes someone else’s copyright, trademark or other rights;
• anything else that is illegal where you or the people you send it to are.

You must also not: try to get into accounts, chats or data that are not yours; interfere with SYNC or overload it; use bots, scrapers or automated accounts; reverse-engineer the app except where the law allows it; or use SYNC to get around a suspension.

Breaking these rules leads to removal of the content and, depending on how serious it is, a warning, a suspension or the permanent closure of the account. Sexual content involving minors, credible threats of violence and terrorist content close the account at once, and we report them to the competent authorities.

5. Reporting, blocking and moderation

• Report: touch and hold a message and choose Report.
• Block: in a one-to-one chat, open the chat’s details and choose Block; in a group, open its members and block the member. You then no longer see that person’s messages and invitations.
• By email: write to [email protected] with the account’s name, the chat, the date and time and, if you can, a screenshot. Anyone, with or without a SYNC account, can tell us about illegal content this way. This address is also our point of contact under the EU Digital Services Act, in English or Russian.

Automatic filter: our servers automatically check every message (its text, the names of attached files and reactions), every group name and description, the name you sign up with and any new name you take in a chat against a list of slurs, threats and terms linked to the sexual exploitation of children. What matches is refused: the message is not sent, or the name is not set. No person reads your messages for this check. If you think something was refused by mistake, write to [email protected].

Our moderators review every report within 24 hours. When content breaks these Terms or the law, we remove it and act against the account that posted it: a warning, a suspension or closure. We may also act on our own when we learn of a violation.

When we remove your content or suspend your account, we email you what we did and why, unless the law or someone’s safety prevents it. If you think we got it wrong, write to [email protected] within 6 months; someone who was not involved in the first decision reviews it.

6. Your content

What you send stays yours. You give us a worldwide, non-exclusive, royalty-free licence to store, copy, transmit and display it only as needed to deliver it to the people you send it to and to run SYNC. The licence ends when the content is deleted from our servers.

We do not use your messages, voice messages or media for advertising or to train artificial intelligence models.

You are responsible for what you send and must have the right to share it. The people you write to can save, forward or screenshot what you send; deleting a message removes it from SYNC, not from copies others have made.

7. Turning voice messages into text

Any member of a chat can ask SYNC to turn a voice message in that chat into text, including a voice message that someone else sent. The recording is then sent to our speech-recognition service, which runs on rented RunPod cloud servers. The text is shown only to members of that chat who ask for it, is kept on our server for up to 24 hours and is never added to the chat. It is made automatically and can contain mistakes.

If you do not want your voice to be transcribed, send a text message instead. Details are in the Privacy Policy.

8. Suspension and closure

We may suspend or close your account, without notice where necessary, if you break these Terms or the law, if you are under 16, if your account puts other people or SYNC at risk, or if the law requires it. Where we can, we tell you why (see Reporting, blocking and moderation).

We may also stop offering SYNC. We will tell you at least 30 days before, in the app or by email, unless legal or security reasons force us to stop sooner.

9. Deleting your account

You can delete your account at any time in the app: Settings › Account › Delete account, confirmed with your password.

Deletion takes effect at once: you can no longer sign in, you are signed out on every device, your contacts, invitations and notification registrations are removed, and chats show you as “Deleted account”. Then, normally within 24 hours and at the latest within 30 days, the messages you sent are removed from every chat and the files you uploaded are deleted from our servers and storage. Reactions you added stay, shown as “Deleted account”. Your email address becomes free, so you can sign up again later with a new account.

A deleted account cannot be restored. What we keep after a deletion, and why, is in the Privacy Policy.

10. No warranty

SYNC is provided “as is” and “as available”. As far as the law allows, we give no warranties, express or implied, including of merchantability, fitness for a particular purpose and non-infringement.

Nothing in these Terms takes away rights you have as a consumer that a contract cannot exclude.

11. Limitation of liability

As far as the law allows, we are not liable for indirect or consequential loss, for loss of data or profits, or for what other users send. Because SYNC is free, our total liability to you for all claims is limited to EUR 100.

We do not limit our liability for death or personal injury caused by our negligence, for fraud, for intent or gross negligence, or where the law does not allow a limit.

12. If you got SYNC from the App Store

• These Terms are between you and AXIOMIC LTD only, not Apple. We, not Apple, are solely responsible for SYNC and its content.
• Your licence to the app is a non-transferable licence to use it on Apple-branded products that you own or control, as the Usage Rules of Apple’s Media Services Terms and Conditions permit.
• Apple has no obligation to provide maintenance or support for SYNC; we provide support (see Support).
• If SYNC fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any (SYNC is free). As far as the law allows, Apple has no other warranty obligation for SYNC.
• We, not Apple, are responsible for addressing any claims by you or a third party relating to SYNC or your possession and use of it, including product liability claims, claims that SYNC fails to meet a legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
• If a third party claims that SYNC or your possession and use of it infringes their intellectual property rights, we, not Apple, are solely responsible for investigating, defending, settling and discharging that claim.
• You confirm that you are not in a country subject to a U.S. Government embargo or designated by the U.S. Government as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties.
• You must comply with the third-party terms that apply when you use SYNC, such as those of your mobile network or Wi-Fi provider.
• Apple and its subsidiaries are third-party beneficiaries of these Terms, and once you accept them, Apple has the right to enforce them against you as a third-party beneficiary.

13. Changes to these Terms

We may update these Terms, for example when SYNC changes or the law requires it. Before a material change takes effect, we tell you in the app at least 14 days ahead, unless the law or safety requires it sooner, and ask you to accept the new version; if you do not agree, you can delete your account. The version and date are at the top of this page.

14. Governing law and disputes

These Terms are governed by the laws of the Republic of Cyprus, and the courts of Cyprus have jurisdiction. If you are a consumer living in another EU country, you keep the protection of that country’s mandatory law and may also bring a claim in its courts.

Please contact us first: most problems can be solved by email. If a part of these Terms is found invalid, the rest remains in force.
