The agreement, written
so you can read it.

These terms are a contract between you (the user) and the operator of Tacitus Mail ("we", "us", "Tacitus"). By registering or using the service, you agree to them. If you don't, please close your account — we don't want to bind anyone against their will.

1. What Tacitus provides

Tacitus Mail is an all-in-one private communications service consisting of:

• A hosted mailbox at your chosen @tacitusmail.com address with SMTP send, IMAP / JMAP-style sync, folders, filters and search.
• Connectors that fetch and display mail from third-party IMAP/SMTP providers you configure (Gmail, Outlook, iCloud, Yahoo, etc.).
• End-to-end encrypted 1:1 chat with other Tacitus users.
• WebRTC peer-to-peer audio and video calls with other Tacitus users.
• A calendar (CalDAV), notes, and a contact address book.
• Web and iOS clients for the above.

2. Account eligibility

• You must be at least 16 years old, or the minimum digital-consent age of your jurisdiction, whichever is higher.
• You must provide a working email or username we can use to reach you about the service.
• You are responsible for keeping your password safe. If you lose it, we can reset it via the forgot-password flow — but we cannot recover mail that was stored under a password you have forgotten and never backed up.

3. Acceptable use

You agree not to use Tacitus Mail to:

• Send unsolicited bulk mail (spam), phishing, scam, chain letters or pump-and-dump.
• Distribute malware, ransomware, exploit kits, or links that lead to them.
• Harass, threaten, stalk, dox or defame another person.
• Generate or share sexual content involving minors. Immediate account termination and reporting to competent authorities; non-negotiable.
• Infringe copyright, trademarks or trade secrets of third parties at commercial scale.
• Attempt to compromise the service — including brute force, denial of service, reverse-engineering the server, exploiting vulnerabilities in production, or bypassing rate limits.
• Resell access to the service without a written agreement with us.

Violating any of the above may result in immediate suspension, account termination, forwarding to law enforcement where legally required, and in all cases a refund equal to zero.

4. Your content belongs to you

Everything you put into your mailbox, chat, calendar, notes or contacts is your content. We do not claim ownership of it. We hold a narrow licence to store, copy, transmit and display your content solely to provide the service you asked for (delivering your mail, syncing to your devices, showing it in the web UI). We do not use it for anything else — see the privacy policy.

5. Plans and billing

• The Free plan is free, forever, with the storage quota and feature set advertised on the pricing page at the time you sign up.
• The Plus and Unlimited plans are paid subscriptions processed by Stripe in EUR. VAT is added where legally required.
• Subscriptions auto-renew on the billing cycle you chose (monthly or yearly) until you cancel. You can cancel at any time from /settings/billing; the cancellation takes effect at the end of the current period.
• If Stripe is unable to charge the renewal after reasonable retries, your plan downgrades to Free and any data over the Free quota becomes read-only until you upgrade again or export it.
• Refunds: we refund the unused portion of an annual plan on written request within 30 days of the renewal charge, at our discretion, in line with EU consumer law. No refunds for monthly plans.
• Prices can change with 30 days' notice by email to the address on the account; you can cancel before the new price takes effect without penalty.

6. Suspension and termination

We can suspend or terminate an account if:

• It violates the acceptable-use policy in section 3.
• It has not been logged into for 12 months AND is on the Free plan. We send a warning to the recovery address 30 days before any data is purged.
• A competent EU judicial authority orders us to.
• Continuing to serve the account would materially endanger other users (e.g. it is the source of a spam outbreak or a compromised account being used for phishing).

You can terminate your account at any time from /settings/accounts or by writing to [email protected]. Data purge timelines are in the privacy policy.

7. Service availability

We aim for 99.9% uptime measured on a rolling monthly basis and we publish honest incidents when we miss it. However, Tacitus Mail is not a life-safety system. You are responsible for keeping independent copies of anything you cannot afford to lose. We are not liable for:

• Mail delivery failures caused by third-party providers marking our IP as spam (we will always fight to clear our reputation).
• Mail delivery failures caused by external providers you've added as connected mailboxes suddenly changing their IMAP/SMTP auth requirements.
• Data loss caused by a force majeure event (data centre fire, act of state, war). We maintain encrypted off-host backups but cannot guarantee zero data loss in every scenario.

8. Limitation of liability

To the maximum extent permitted by EU consumer law, our aggregate liability to you for any claim arising out of your use of Tacitus Mail is limited to the greater of €100 and the total fees you paid us in the 12 months preceding the claim. We are never liable for indirect, lost- profit, lost-opportunity or consequential damages. None of this limits any liability that cannot be excluded under applicable EU consumer law.

9. Changes to these terms

We can update these terms with 30 days' notice to the email address on your account. If you keep using the service after the new terms take effect, you accept them; if you don't, you can terminate within the notice period without penalty and export your data per section 5.

10. Governing law & disputes

These terms are governed by the law of the European Union member state in which Tacitus is established. Disputes are subject to the exclusive jurisdiction of the courts of that member state — but before going to court, please write to [email protected] and give us a chance to fix whatever is wrong. In most cases we can.

If you are an EU consumer, the European Commission provides an Online Dispute Resolution platform at ec.europa.eu/consumers/odr.
