Terms of Service.

By downloading or using AlterSend, you agree to these Terms. Short version: don't use it for anything illegal, and understand that files transfer directly between devices — we never see them.

1. What AlterSend does

AlterSend is operated by Devaprime LLC ("we", "us"). AlterSend lets you transfer files directly between two devices. All transfers are encrypted end-to-end. In most cases files travel directly between devices; if a direct connection isn't possible (for example, both devices are behind a VPN), encrypted data may pass through a relay server we operate. The relay is on by default and can be turned off in the app. Either way, we never have the ability to decrypt, store, or view the files you transfer.

2. Acceptable use

You may use AlterSend only for lawful purposes. You must not use AlterSend to transfer, receive, or distribute content that is illegal in your jurisdiction, including but not limited to child sexual abuse material (CSAM), content that glorifies violence or terrorism, or content that infringes third-party intellectual property rights. You must not send malware, ransomware, spyware, or any software designed to damage, monitor, or gain unauthorised access to another device. You must not harass, threaten, or abuse another person, or circumvent any applicable laws or regulations. These rules apply whether a transfer completes directly between devices or passes through our optional relay servers. We have zero tolerance for objectionable or abusive content and will take appropriate action, including blocking specific devices from using the relay, against users who violate these rules.

3. Reporting abusive content

If you receive content through AlterSend that you believe is illegal or violates these Terms, please report it immediately. In-app: use the "Report this content" link on the download-complete screen. By email: send a description to abuse@altersend.com. We review all reports and will act within 24 hours for reports of illegal content.

4. Your content and responsibility

You are solely responsible for the files you choose to send or receive using AlterSend. Because all transfers are end-to-end encrypted — whether direct or relayed — we cannot decrypt, screen, or moderate content in real time. You represent that you have the right to transfer any file you send, that the content you transfer complies with these Terms and applicable law, and that you will not use AlterSend to send content to someone who has not consented to receive it.

5. Open-source software

AlterSend is released under the Apache 2.0 license. The source code is available at github.com/denislupookov/altersend. Your use of the source code is governed by that license, not these Terms.

6. No warranty

AlterSend is provided "as is" without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the app will be error-free, uninterrupted, or that transfers will always complete successfully. Peer-to-peer networking inherently depends on network conditions outside our control.

7. Limitation of liability

To the maximum extent permitted by applicable law, we are not liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of AlterSend, including loss of data, loss of files, or damages arising from content transferred through the app. Our total liability to you for any claim shall not exceed the amount you paid for the app (which is zero, as AlterSend is free).

8. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will update the "Last updated" date at the top of this page. Continued use of AlterSend after changes are posted constitutes your acceptance of the new Terms.

9. Governing law

These Terms are governed by and construed in accordance with the laws of the jurisdiction in which AlterSend is operated. Any disputes shall be resolved in the competent courts of that jurisdiction.

10. Tips

By making a financial contribution (“tip”) to support the development or maintenance of the Software, you acknowledge and agree that:

  • All tips are made voluntarily and without expectation of any goods, services, or other benefits in return. Tips do not constitute a purchase, investment, or any form of consideration for current or future services.
  • All tips are final and non-refundable, regardless of whether the Software’s development continues, is modified, suspended, or discontinued.
  • A tip does not grant you any ownership, intellectual property rights, or other legal interests in the Software, its source code, or related projects.
  • Tips may be used at the sole discretion of the Company to support the development, maintenance, or related operational costs of the Software.
  • Maintainers and/or the Company are under no obligation to act upon suggestions, requests, or expectations made by donors, unless explicitly agreed upon in writing.
