Terms of service

Effective 2026-11-11. These terms govern the use of PeriodGuard (https://periodguard.com), a service operated by Tenhatch, 26500 W Agoura Rd, Ste 102 #549, Calabasas, CA 91302, United States ("we", "us"). By creating an account or calling the API you agree to them.

1. The service

PeriodGuard keeps a history of changes to the accounting records of the businesses you connect from Xero, alerts you when a change lands in a closed period, and gives you the history through a web application and an API. We may change or improve the service at any time; we will not remove the core feature from a paid plan during a paid period without a refund.

PeriodGuard only reads your records, with the read-only access you grant in Xero; it never changes them. It finds changes at its next snapshot, so it can be up to an hour late on a paid plan, and it cannot show a change made before you connected the business. Who made a change is what Xero's own history of the record says. PeriodGuard is a record of what it found; it is not an audit, does not give accounting, tax or legal advice and does not replace your own records or backups.

2. Accounts

You need an account to use the service beyond the public pages. You are responsible for what happens under your account and for keeping sign-in links and API keys secret. Tell us at support@tenhatch.com at once if a key leaks; revoke it from the account page.

Connect only businesses you are allowed to give access to, such as your own or a client's who has agreed. You can disconnect a business at any time; everything we stored about it is then deleted, as the privacy policy describes. Your use of Xero itself stays under Xero's own terms.

3. Plans, billing and usage

• Prices and included usage are listed on the pricing page and in the account. Prices exclude taxes unless stated.
• Subscriptions renew automatically at the end of each period (monthly or annual) until cancelled. Cancel at any time from the account page; the plan stays active until the end of the paid period.
• Each plan covers a number of businesses; connecting more needs a bigger plan. Businesses beyond the plan are paused, never charged extra.
• API and agent queries above a plan's allowance are not possible without upgrading, except on pay-as-you-go pricing for paid accounts, charged at the per-query price shown on the pricing page.
• Refunds are governed by our refund policy: 14 days, no questions asked.

4. Acceptable use

Do not use the service to break the law, to infringe others' rights, to send content you have no right to process, or to attack, overload or reverse engineer the service. Automated access is welcome through the API and the MCP server within the published rate limits; scraping the web application is not.

5. Your content

You keep all rights to your records and everything we read from Xero for you. You grant us the limited right to store and process them only to provide the service to you. We never sell or share them, never use them to train any AI model, and delete them according to the privacy policy.

6. Availability and support

We aim for high availability but the service is provided "as is" without a guaranteed uptime. Support is by email at support@tenhatch.com and through the in-app assistant.

7. Liability

To the extent permitted by law, our total liability for any claim arising from the service is limited to the amount you paid us in the 12 months before the claim. We are not liable for indirect or consequential loss. Nothing in these terms limits liability that cannot be limited by law.

8. Termination

You may close your account at any time. We may suspend or terminate accounts that break these terms, with notice where reasonable. On termination your access ends and your data is deleted according to the privacy policy.

9. Changes

We may update these terms. Material changes are announced by email or in the application at least 14 days before they take effect. Continued use after that date means you accept the new terms.

10. Governing law

These terms are governed by the law of California. Disputes are brought before the courts of California, unless consumer law gives you the right to another venue.
