Tacq Terms of Service
Welcome to Tacq — a managed contact platform developed and maintained by the independent Tacq Team. By using the Tacq application, you agree to these rules.
1. Nature of the Service
Tacq is a tool for establishing secure connections ("anonymous handshakes"). Tacq provides technology to create isolated communication sessions without the need to reveal your personal data.
Tacq is intended for users aged 13 and older. By using Tacq, you confirm that you are at least 13 years old; people under 13 may not use the app.
2. Account Security
Since Tacq does not link accounts to a phone number or personal email, traditional password recovery (via SMS or email) is impossible. You are solely responsible for the security of your password, the generated Master ID and your recovery phrase. The recovery phrase is the only way to restore access to your account if you forget the password or lose your devices; without it, restoring access is technically impossible.
3. Your Responsibility for Content
The Tacq system does not require you to enter personal data (PD). However, if you voluntarily choose to share your real name, phone number, bank details, or sensitive documents in a chat, you bear full responsibility for the distribution of this information. Tacq strongly recommends sharing sensitive information only with interlocutors you fully trust. If you use the "Top secret" mode, the content of those messages is available only on the device where the chat is held and is not backed up on Tacq’s servers — if you lose or change that device, this history cannot be recovered.
4. Session Isolation and Prohibition of Transfer
Each communication session (chat) in Tacq is unique and belongs only to its participants (or the owning organization in the case of business accounts). You may not sell, rent, or otherwise unlawfully transfer access to your account to third parties.
5. Unacceptable Behavior and Spam Protection
Tacq is created for productive and secure communication. It is strictly forbidden to:
- Engage in any form of child sexual abuse or exploitation (CSAE), including grooming, sexualizing a minor, or sharing child sexual abuse material (CSAM).
- Use the platform for spamming, mass unsolicited invitations, or creating automated botnets.
- Publish, upload, or distribute illegal, extremist content, or materials that infringe on copyrights.
- Use the system to threaten, blackmail, or harass other users.
Tacq has zero tolerance for CSAE and acts on it under its Child Safety Standards: offending content is removed, the account is permanently banned, and Tacq reports to the appropriate authorities where required by law.
The Tacq Team reserves the right to apply automated Rate Limits to protect the infrastructure from flooding and DDoS attacks.
6. Blocks, Reports, and Conflict Resolution
You have two tools to control your communication. First, the "Block" button: if an interlocutor behaves inappropriately, you can instantly sever the connection — a blocked session permanently loses the ability to send messages or make calls unless you unblock it. Second, the "Report" button: if a message or a person violates the law or these Terms — for example threats, bullying or harassment, intimate images shared without consent, or content that endangers children — you can send a report to the Tacq Team. Tacq reviews the reports it receives and, under these Terms and its Child Safety Standards, may block the offender’s account: it can then no longer send messages, make calls or start new sessions. Tacq cannot delete messages that have already been delivered: they are kept on the participants’ devices, and Tacq has no access to them. You can delete them on your side and block the other person yourself. Tacq does not guarantee a specific outcome or a response time for any individual report.
7. License to Use Tacq, and Tacq’s Intellectual Property
Tacq grants you a personal, limited, non-exclusive, non-transferable, revocable license to use the app for your own communication, subject to these Terms. The Tacq software, name, logo, design, and all related intellectual property belong to the Tacq Team and are protected by law (patent pending, U.S. Patent Application #64/026,998). You may not copy, modify, reverse-engineer, resell, or create derivative works from the app except as permitted by mandatory law. If you send Tacq feedback or suggestions, you allow Tacq to use them freely, without obligation or payment to you.
8. Third-Party Services
Tacq relies on third-party infrastructure — including Google Firebase (hosting, database, notifications), Hetzner (hosting of Tacq’s own call relay server in Germany), and the app stores through which you install Tacq. Your use of Tacq may also be subject to those providers' own terms. Tacq is not responsible for third-party services, and their availability or changes are outside Tacq’s control.
9. Not for Emergencies
Tacq is a communication app, not a telephone, carrier, or emergency service. You cannot use Tacq to contact emergency services (such as 112, 911, 101, 100, or 102) and you should not rely on it in an emergency. Message and call delivery depend on the internet, your device, and third-party networks, and are not guaranteed. Always keep another way to reach emergency services.
10. Availability, Changes, Suspension, and Termination
Tacq may change, improve, limit, suspend, or discontinue any part of Tacq at any time, including during early access or a pilot, when features may still change and are provided without any guarantee. Tacq may suspend or permanently block an account (Master ID) that violates these Terms, the Child Safety Standards, or applicable law, or where necessary to protect users or the service. You may stop using Tacq and delete your account at any time. Sections that by their nature should survive termination (for example 3, 7, 11, 12, 13, 15, 16, and 18) continue to apply after your account ends.
11. Disclaimer of Warranties ("As Is")
Tacq is provided "as is" and "as available", without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, and availability. Tacq does not warrant that the service will be uninterrupted, timely, secure, error-free, or free of harmful components, or that any message or call will be delivered. While Tacq encrypts conversations end to end, no security method is perfect: Tacq does not warrant that encryption cannot be broken or that communications cannot be intercepted, and you use these features at your own risk. Tacq is not responsible for the conduct, content, or data of any user or third party. Some jurisdictions do not allow certain warranty exclusions, so parts of this section may not apply to you.
12. Limitation of Liability
To the fullest extent permitted by law, the Tacq Team will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, goodwill, or communications, arising out of or related to your use of (or inability to use) Tacq, even if the Tacq Team was advised of the possibility. To the fullest extent permitted by law, the Tacq Team’s total aggregate liability for all claims relating to Tacq is limited to fifty US dollars (US$50). Nothing in these Terms limits liability that cannot be limited under applicable law, including liability for fraud, willful misconduct, or death or personal injury caused by the Tacq Team’s negligence.
13. Indemnification
To the extent permitted by law, you agree to indemnify and hold harmless the Tacq Team from any claims, liabilities, damages, losses, and reasonable expenses (including legal fees) arising from your content, your use of Tacq, your violation of these Terms, or your violation of any law or the rights of another person.
14. Reporting Intellectual-Property Infringement
Tacq respects intellectual-property rights. If you believe content on Tacq infringes your copyright or trademark, contact Tacq at support@tacq.app with: a description of the work, where the material is located, your contact details, and a statement that you have a good-faith belief the use is unauthorized. Tacq will review valid notices and may remove infringing content and act against repeat infringers.
15. Export Control and Sanctions
You may not use Tacq if you are located in, or are a national or resident of, a country or territory subject to comprehensive government embargo, or if you are on a relevant restricted-party or sanctions list. By using Tacq, you confirm that this is not the case and that you will not use Tacq for any purpose prohibited by applicable export-control or sanctions laws.
16. Governing Law and Dispute Resolution
These Terms, and any dispute arising out of or relating to them or to Tacq, are governed by the laws of the State of Israel, without regard to conflict-of-law rules. The competent courts of Israel will have jurisdiction over such disputes. Any claim must be brought individually, and not as a plaintiff or class member in any class, collective, or representative action. This section does not deprive you of any mandatory consumer-protection rights available to you under the law of your country of residence, which continue to apply where they cannot be waived by agreement.
17. Changes to These Terms
Tacq may update these Terms from time to time. When Tacq makes material changes, it will update the date and, where appropriate, notify you within the app or on the Tacq website. Your continued use of Tacq after the changes take effect means you accept the updated Terms. If you do not agree, stop using Tacq and delete your account.
18. General
If any provision of these Terms is found unenforceable, the rest remain in effect. These Terms are the entire agreement between you and the Tacq Team regarding Tacq. The Tacq Team’s failure to enforce a provision is not a waiver of it. You may not transfer your rights under these Terms; the Tacq Team may transfer its rights to a successor (for example, to a company that continues Tacq). The Tacq Team is not liable for failures caused by events beyond its reasonable control (force majeure). Notices to you may be given within the app, by the contact you provided, or on the Tacq website. These Terms are published in English, Russian, Hebrew, French, Spanish and German; if there is a conflict between versions, the English version prevails, except where local law requires otherwise.
