Acceptable Use Policy
Effective November 8, 2026
This policy is part of the Cairn Terms of Service. It describes what you may and may not do with the Cairn service operated by Cairn Labs, Inc. ("Cairn"). It exists to protect other users, the employers and providers whose systems Cairn reads, and the Service itself.
1. Permitted use
You may use Cairn to track, understand and manage your own job search, or the job searches of members of an organization that has purchased seats for them. You may forward or connect mailboxes you control, open portal pages in accounts you own, store your own credentials and keys, and message Cairn from your own phone or chat accounts.
2. Prohibited use
You may not use the Service to:
- Access, or attempt to access, data belonging to another user or account.
- Forward, connect or store email, portal data or credentials that you are not entitled to use.
- Submit applications, messages or forms to employers automatically. Cairn does not do this, and you may not build on Cairn to do it.
- Send unsolicited messages, including bulk outreach to recruiters or employees of a company.
- Circumvent rate limits, authentication, robots directives, or the terms of a job board, applicant portal or messaging provider.
- Scrape or crawl websites through the Service beyond the public board APIs and public records Cairn reads on your behalf.
- Misrepresent your identity, qualifications or employment history in content you ask Cairn to generate or store.
- Upload malicious code, probe or test the vulnerability of the Service without written permission, or interfere with its operation.
- Reverse engineer, decompile or disassemble the Service except where the law expressly permits.
- Resell, sublicense or offer the Service to third parties without an agreement with Cairn.
- Use the Service in violation of applicable law, including anti-discrimination, privacy, telecommunications and export-control laws.
3. Messaging rules
If you link a phone number or chat account, you confirm it is yours. You may not link a number belonging to another person. You may not use Cairn's messaging channels to contact anyone other than Cairn. Reply STOP at any time to end SMS messages; reply HELP for help.
4. Portals and the browser companion
The companion reads only pages you open in your own browser. Portal sync, where available, signs in with credentials you stored and reads status pages. Neither will submit applications or change portal data. You may not use either to access an account that is not yours, to defeat anti-automation measures, or against a portal whose terms forbid automated access.
5. Models and bring-your-own-key
If you store your own model-provider key, you must comply with that provider's usage policies. You may not use Cairn's platform model budget for purposes unrelated to your job search, or attempt to extract system prompts, other users' data or training data from a model through the Service.
6. Security research
We welcome good-faith security research under the responsible disclosure terms on the Security page. Report findings to security@getoncairn.com. Do not access, modify or exfiltrate data that is not yours, do not degrade the Service, and give us a reasonable time to fix an issue before disclosing it. We will not pursue legal action against researchers who follow these rules.
7. Enforcement
If we believe you have breached this policy, we may warn you, pause a feature such as messaging or portal sync, suspend your account, or terminate it. Where practical we will tell you what happened and give you a chance to export your data. We may also report unlawful activity to authorities. Section 14 of the Terms of Service applies.
8. Reporting abuse
To report misuse of the Service, write to abuse@getoncairn.com. Include the account, the behaviour and the time. We respond to every report.
9. Changes
We may update this policy with the Terms of Service. Material changes are notified at least 30 days before they take effect.
