Terms and Conditions

Version 2026-09-26-draft

Draft. This text is provisional and has not been reviewed by a lawyer. Parts in [square brackets] are still to be decided.

1. About these terms

These Terms and Conditions govern your use of argus0 (the "Service"), provided by [company name, registered office, registration number] ("we", "us"). By creating an account, or by continuing to use the Service after being asked to accept a new version, you agree to them.

2. The Service

argus0 receives the DMARC aggregate reports that mail receivers send about your domains, and shows what they say: who sends mail as your domains, whether it passes SPF, DKIM and DMARC, and what changed. It checks your published DNS records. It does not change your DNS: any change is made by you, at your DNS provider.

3. Your account

You must give accurate details and keep your password to yourself. You are responsible for what is done through your account, including by guests you let in, AI assistants you connect and feed tokens you create. Tell us promptly at [contact address] if you think someone else has access.

4. Acceptable use

Add only domains you own or are authorised to monitor. Do not use the Service to send spam, to attack or probe systems you are not authorised to test, to overload it, or to get around its limits or security.

5. Your data

The reports we receive for your domains contain the IP addresses and host names of servers that sent mail as them. We keep report data for as long as your plan's retention allows and delete it after that. You can ask for your account and its data to be exported or deleted. How we process personal data is set out in our Privacy Policy. For the report data we process on your behalf, see the Data Processing Agreement and the list of sub-processors [whether the DPA is accepted with these terms: to be decided with counsel].

6. Plans and fees

The features and limits of each plan are described on the pricing page. [Billing, renewal, cancellation and refund terms to be written.]

7. Availability and no warranty

We work to keep the Service available and accurate, but provide it "as is". Reports depend on third parties choosing to send them, and geolocation data is an estimate. [Service level, if any, to be decided.]

8. Liability

[Limitation of liability to be written, within what the applicable law allows.]

9. Suspension and termination

You may close your account at any time. We may suspend or close an account that breaks these terms, after telling you why where we reasonably can. [Notice periods and what happens to data on closure to be decided.]

10. Changes to these terms

We may change these terms. When the change is one you must agree to, you will be asked to accept the new version the next time you use the Service, and you can close your account instead.

11. Governing law

[Governing law and competent courts to be decided.]

12. Contact

[Contact address for questions about these terms.]

13. Third-party data and software
