Terms of service

Last updated: 2026-10-21. Effective: 2026-11-05. Version: 2026-11-05.

These terms govern the use of Tatamo, the online software for managing dojos, and its public website. Read them together with the Acceptable use policy, the Cancellation and refunds policy and the Privacy notice.

Tatamo is operated by El Sheimus Platform, at P.º de San Francisco, Col. Misión de Guadalupe, C.P. 67117, Guadalupe, N.L., Mexico ("Tatamo").

Whoever creates or manages a workspace (the "dojo") accepts these terms, the Acceptable use policy, the Cancellation and refunds policy and the Privacy notice by ticking the acceptance box.

Tatamo keeps a record of the accepted version, the date, the IP address and the browser. This electronic acceptance is fully valid (Federal Civil Code, art. 1803; Commercial Code, arts. 89 et seq.).

Tatamo offers Gratis with every base-service feature and the Tatamo IA subscription for $149 MXN/month, VAT included. Gratis and Tatamo IA include 60 students with portal access and 2 team seats for staff and instructors; the owner does not count. Tatamo Insignia and Insignia + IA are not available yet.

Direct signup is free and open. If you need more students or instructors, request capacity from Settings > Plan. Tatamo staff adjust limits; pricing is agreed case by case and is not published. AI packs are separate optional purchases (section 10).

3. Tatamo IA and Tatamo Insignia (coming soon)

Tatamo Insignia ($99 MXN/month) and Insignia + IA ($199 MXN/month), VAT included, are not available yet and cannot be bought. Their terms will be published here before they can be bought.

Tatamo IA costs $149 MXN/month, VAT included, and adds 500 monthly messages to any plan. It is billed in advance, with automatic renewal to the authorized payment method through Stripe. Billing is monthly only. You may cancel in Settings > Plan anytime without penalty; cancellation takes effect at the end of the paid period. There are no partial refunds except for duplicate or erroneous charges or where required by law. The monthly allowance refills on the 1st in the workspace time zone, does not roll over and is spent before packs. Pack terms remain unchanged.

If payment fails, there is a 7-calendar-day grace period to resolve it; the workspace then returns to Gratis. Price changes are announced at least 15 calendar days in advance.

If Tatamo staff assign Insignia to a workspace, it receives 50 extra AI messages per month while the assignment lasts.

These are governed by the Cancellation and refunds policy, available at /refunds.

The dojo agrees to:

  • Provide truthful information and keep its credentials secure.
  • Obtain the consents and give its own privacy notice to its students, guardians and staff. The dojo is the controller of that data; Tatamo acts as processor and handles it only to provide the service.
  • Comply with the law in its relationship with its students, including prices, appointments, charges and deposits.
  • Comply with the Acceptable use policy.
  • If it records data of minors, have the consent of their parent or guardian.

Tatamo may warn, suspend or close an account for the reasons in the Acceptable use policy. The process is: (1) written notice stating the cause and 5 business days to correct it; (2) suspension; (3) closure.

Suspension is immediate, without prior notice, in these cases: fraud, security risk, illegal content or harm to third parties. Every measure is notified to the dojo email with its reason, and the dojo may respond at soporte@tatamo.app.

During suspension the workspace cannot be used and the public booking page is paused. Data is kept.

The dojo may close its account at any time. After any closure, the dojo has 30 calendar days to download an export of its data. When that period ends, the data is permanently deleted. Only what the law requires us to keep, such as tax or billing records, is retained.

We work to keep the service available but do not guarantee uninterrupted service. Scheduled maintenance is announced in advance when possible.

Support is handled at soporte@tatamo.app on business days. We reply within 2 business days at most.

The software and the marks belong to Tatamo or its licensors. The dojo's data belongs to the dojo.

The AI assistant is optional. You can use Tatamo without it. One message means one user request, even when several internal queries are needed to answer.

Gratis includes 20 AI messages per month. Tatamo IA adds 500 monthly messages, for a total of 520. The allowance refills on the 1st in the workspace time zone and does not roll over. The daily cap is 50 messages per workspace, including pack messages.

100 messages for $49 MXN, 500 for $149 MXN and 2000 for $399 MXN, VAT included. Launch offer when paying by card in the app: 100 + 50 free, 500 + 250 free and 2000 + 1000 free; the free messages are added to the pack and last just as long. Available to everyone, valid for 12 months from purchase. Included monthly messages are used first, then the oldest pack. Included monthly messages do not roll over. Unused pack messages expire without refund. The legacy 300-message pack keeps its original validity.

Used messages are not refundable. An unused pack may be refunded if requested within 10 days of purchase, under the Cancellation and refunds policy. Launch-offer free messages have no cash value and are not refunded separately. The offer has no end date; if we end it, we will announce it beforehand on this page and in the app; packs already paid for keep their free messages.

Answers may contain errors or be incomplete. Check them before making decisions; the assistant does not replace your judgment or professional advice.

The assistant only reads dojo information (for example students, attendance, schedules and fees your user can already access). It does not create, change or delete data.

The current AI provider is Anthropic (Claude), in the United States. Your message and relevant dojo data your user can access are sent to generate a response. We may switch to other providers through OpenRouter, with notice in the Privacy notice. Do not include information you do not want to share with them.

Tatamo is liable for failures attributable to it under applicable law. Otherwise, its total liability is capped at the amounts paid to Tatamo in the 12 months preceding the event, for the Tatamo IA subscription and AI message packs.

Tatamo is not liable for the dojo's decisions about its students, for charges the dojo makes, or for third-party failures beyond its control. Nothing in these terms limits rights that the law does not allow to be waived.

Material changes are announced at least 15 calendar days in advance, by email and inside the app. To keep using the service you will need to accept the new version. If you disagree, you may cancel without penalty.

These terms are governed by the laws of Mexico. Any dispute will be resolved before the courts of Monterrey, Nuevo León. This does not affect the right to go to PROFECO where applicable.
