Terms of Use
Hollow
Last Updated: May 1, 2026
These Terms of Use ("Terms") govern your access to and use of the Hollow application and related services ("Services") provided by AnonListen ("we", "us", "our"). By using Hollow, you agree to these Terms.
1. What Hollow is
Hollow is a distributed, end-to-end encrypted communication application. Messages, calls, and files are encrypted on your device and can only be decrypted by the intended recipients. We operate relay infrastructure to facilitate connections between peers, but we do not store, access, or process the content of your communications.
2. Who can use Hollow
You must be at least 13 years old (or the applicable age of majority in your jurisdiction, whichever is higher) to use Hollow.
3. Your account
Your Hollow account is a cryptographic keypair generated on your device. You are responsible for safeguarding your recovery phrase (BIP-39 mnemonic). We cannot recover your account if you lose your recovery phrase — there is no "forgot password" mechanism because we do not have access to your credentials.
4. Acceptable use
You agree to use Hollow only for lawful purposes. You agree not to use Hollow to:
- Engage in any activity that violates applicable law
- Distribute child sexual abuse material (CSAM) or exploit minors
- Coordinate, promote, or glorify terrorism or violent extremism
- Engage in targeted harassment, stalking, or threats of violence
- Distribute malware or harmful software
- Attempt to compromise Hollow's relay infrastructure or other users' devices
- Use automated means to create accounts or send messages in bulk
5. Content and conduct
You own the content you create and share through Hollow. We do not claim any rights to your content.
Because Hollow uses end-to-end encryption, we cannot access, review, moderate, or remove the content of your messages, calls, or files. Our Services have been designed using a privacy-by-design approach, which means it is technically impossible for us to analyze or monitor the content you create, send, or receive through Hollow.
Individual Hollow servers are created and managed by their owners. Server owners may set their own rules and moderate their own communities. We are not responsible for the moderation practices of individual server owners.
If you become aware of any use of Hollow that violates these Terms, you may report it to us at privacy@anonlisten.com.
6. Software ownership and your rights
The Hollow application code, trademarks, and associated branding are the intellectual property of AnonListen (Vitalii Rovinskyi).
You own your copy of Hollow. Once you download Hollow, it is yours. We cannot remotely disable, lock, or revoke your installed copy of the application. Your data, your keys, and your messages belong to you — not to us.
Hollow is intended to become fully open-source. In the event that AnonListen ceases to operate, the complete source code will be released under a permissive open-source license.
7. Disclaimers
The Services are provided "as is" and "as available" without warranties of any kind. We disclaim all warranties, including merchantability, fitness for a particular purpose, and non-infringement.
You use Hollow at your own risk. You are solely responsible for the content you create, send, and receive, and for compliance with all applicable laws in your jurisdiction.
8. Limitation of liability
To the maximum extent permitted by applicable law, AnonListen will not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Services. Our aggregate liability for all claims shall not exceed ten euros (€10).
9. Stopping use
You may stop using Hollow at any time by deleting the application from your device. This removes all locally stored data. No account deletion request is needed — there is no account on our servers to delete.
10. Mere conduit status
Hollow's relay infrastructure operates as a "mere conduit" within the meaning of the EU Digital Services Act (Article 4). The relay does not initiate transmissions, does not select receivers, and does not select or modify the information contained in transmissions. All content passing through the relay is end-to-end encrypted and opaque to us.
11. Governing law
These Terms are governed by the laws of the European Union and the Republic of Poland. Any disputes shall be resolved exclusively in the competent courts of Poland.
12. Changes to these Terms
We may update these Terms from time to time. Changes will be posted with an updated "Last updated" date. Material changes will be communicated through the application.
