Terms of Service
Last updated: July 10, 2026
These Terms govern your use of the Chesly mobile apps, the website at chesly.app, and related services (the "Service"). By using the Service, you agree to these Terms. Section 14 contains a binding arbitration agreement and a class-action waiver.
1. Eligibility and account
You must be at least 13 (or 16 in the EEA, UK, and other jurisdictions that require this). Your account is identified by a cryptographic recovery phrase that you control and must keep confidential. We cannot recover your account without it. You are responsible for activity under your account.
2. The Service
Chesly, Inc., a Delaware corporation ("Chesly," "we," "us"), operates a unified messaging client that bridges third-party messaging and email providers into a single inbox and may offer optional AI features. Chesly is independent and is not affiliated with, endorsed by, or sponsored by any provider. Provider names and logos belong to their respective owners.
3. Connected accounts
When you link a provider, your use of that provider remains governed by its own terms. You authorize Chesly to access and process the data you make available, solely to operate the Service for you. You can disconnect any provider at any time; doing so removes the Chesly connection but does not delete your account on that provider. Where the connection uses a provider session cookie, browser token, or app-specific password, also revoke that credential with the provider to end the underlying session.
4. License
Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for your personal or internal business purposes. All other rights are reserved.
5. Acceptable use
You agree not to:
- Use the Service unlawfully or to send spam, phishing, malware, harassment, or abusive content;
- Distribute child sexual abuse material or any content that exploits or endangers minors;
- Infringe intellectual-property or privacy rights, or impersonate any person or entity;
- Reverse engineer the Service except where this restriction is prohibited by law;
- Probe, scan, or interfere with the Service except with our prior written authorization (responsible disclosure: security@chesly.app);
- Scrape data from the Service or use it to train competing AI models without our written consent;
- Bypass any restriction in the Service or in a connected provider's terms.
Objectionable content and moderation. Chesly has zero tolerance for objectionable content and abusive behavior. You can report offensive content directly from the message menu and block any user from their profile or the conversation screen; blocked users can no longer reach you through Chesly. We review reports, prioritize reports involving child safety or imminent harm, and may remove violating content or suspend or permanently remove the responsible accounts. We may take this action at our discretion to protect users and to comply with the law. Send child-safety concerns to privacy@chesly.app.
6. Your content and AI
You retain ownership of the messages, files, and other content you transmit through the Service ("Your Content"). You grant Chesly a worldwide, non-exclusive, royalty-free license to host, store, transmit, and display Your Content solely as needed to operate the Service for you. We do not use Your Content to train third-party AI models, and we do not use it to train our own models without your consent. AI outputs may be inaccurate; you are responsible for reviewing them before relying on them.
7. Beta features
TestFlight and other beta builds are provided "AS IS" and "AS AVAILABLE", may change or be discontinued without notice, and are not subject to any service-level commitment. You grant us a royalty-free license to use feedback you provide.
8. Subscriptions and billing
Chesly Plus is an optional auto-renewing subscription that unlocks premium features. Plans may be offered monthly or annually and may include a free trial where shown before purchase. The subscription title, length, price, trial, and renewal terms are shown before you confirm a purchase.
For purchases made through Apple, payment is charged to your Apple ID at confirmation of purchase. Your subscription automatically renews unless you cancel at least 24 hours before the end of the current period, and your account may be charged for renewal within 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple ID account settings. Refunds for Apple purchases are handled by Apple under its policies. If your subscription expires or is canceled, Chesly Plus features may become unavailable at the end of the current paid period.
9. Apple App Store and app marketplaces
These Terms are between you and Chesly only, not Apple or any app marketplace. Apple has no obligation to provide support and is not responsible for the Service or any claim relating to it (including product liability or IP infringement). Apple and its subsidiaries are third-party beneficiaries of these Terms with the right to enforce them. Use of the iOS app is subject to Apple's App Store Terms.
10. Intellectual property
The Service and the Chesly name, logo, software, and content (other than Your Content) are owned by Chesly and its licensors. These Terms grant you no right to use Chesly's trademarks. Copyright complaints: dmca@chesly.app.
11. Suspension and termination
You may stop using the Service and delete your account at any time. We may suspend or terminate access if you violate these Terms or applicable law, if necessary to protect the Service, or if your account is inactive. Sections 5, 6, 10, 12, 13, 14, 15, and 16 survive termination.
12. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, AND WARRANTIES THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE OR THAT AI OUTPUTS WILL BE ACCURATE.
13. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, CHESLY WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL. OUR TOTAL AGGREGATE LIABILITY WILL NOT EXCEED THE GREATER OF THE AMOUNTS YOU PAID TO CHESLY IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR USD $100.
14. Disputes
Before filing a formal dispute, you agree to try to resolve it informally by emailing legal@chesly.app. If the dispute is not resolved within 60 days, it will be resolved by binding individual arbitration (or in small-claims court if eligible). You and Chesly waive any right to bring claims as a class action or representative proceeding. You may opt out of arbitration by sending written notice to legal@chesly.app within 30 days of first accepting these Terms. EU and UK consumers may bring claims in their country of residence where mandatory law so provides.
15. Governing law
These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-laws principles. Nothing in these Terms limits your statutory consumer rights.
16. Indemnity
You will indemnify Chesly against claims arising out of Your Content, your breach of these Terms, or your violation of any third-party right, to the maximum extent permitted by law.
17. Changes
We may update these Terms. Material changes will be notified in-app or by email at least 14 days before they take effect, except where the change is required by law. Continued use after the effective date means you accept the updated Terms.
18. Miscellaneous
These Terms, together with our Privacy Policy, are the entire agreement between you and Chesly. If any provision is unenforceable, the rest remains in effect. We may assign these Terms; you may not without our written consent. Notices to Chesly: legal@chesly.app.
