Terms of service

Last updated October 1, 2026

These terms are an agreement between FONTANA & SYDOW SERVICOS EM TECNOLOGIA LTDA ("we", "us") and the organization that installs or uses MyOnCall ("you"). By adding MyOnCall to a Slack workspace or using it, you agree to them. If you accept on behalf of an organization, you confirm that you're allowed to do so.

1. The service

MyOnCall manages on-call rotations in Slack: it keeps Slack user groups pointed at whoever is on call, handles overrides and swaps, and posts handoff messages and reminders. It runs on Slack, so it depends on Slack being available and on your workspace's plan and settings. For example, Slack only offers user groups on paid plans, and your admins must allow MyOnCall to manage them.

MyOnCall is a scheduling tool, not an alerting or paging system. It doesn't guarantee that anyone is notified of an incident. You remain responsible for your incident response, including having a backup when Slack or MyOnCall is unavailable.

2. Accounts and access

People sign in with their Slack accounts. Your workspace's owners and admins decide who can change rotations, and you're responsible for activity under your workspace and for keeping your Slack accounts secure.

3. Trial, plans and billing

  • Every new workspace starts with a free trial of the Starter plan. The trial length is shown when you install.
  • After the trial, MyOnCall is a paid subscription, billed monthly or annually in advance through Stripe. It renews automatically until cancelled.
  • If the trial ends without a payment method, the subscription pauses and MyOnCall stops updating your user groups until you add one.
  • You can change plans or billing interval from the Billing page. The billing portal shows when a change takes effect and any amount due.
  • Prices don't include taxes, which may be added where they apply.
  • We'll give you at least 30 days' notice before a price change applies to your subscription.
  • Uninstalling MyOnCall cancels your subscription at the end of the current billing period. Payments aren't refunded for partial periods, except where the law requires it.

4. Acceptable use

You agree not to:

  • use MyOnCall for anything illegal or in breach of Slack's terms;
  • interfere with or overload the service, or try to get around its limits or security;
  • copy, resell or reverse engineer MyOnCall, except where the law allows it;
  • use it to build a competing product.

5. Your data

You own your data. You allow us to use it only to provide and support MyOnCall, as described in our privacy policy. We may use aggregated information that doesn't identify you or your members to understand and improve the service.

6. Availability and support

We work to keep MyOnCall running and to fix problems quickly, but we don't promise that it will be available at all times or free of errors. Support is by email at support@myoncall.app.

7. Ending the agreement

You can stop using MyOnCall at any time by uninstalling it from Slack. We may suspend or end your access if you don't pay or seriously break these terms; when we can, we'll warn you first and give you a chance to fix it. After the agreement ends, your data is kept or deleted as the privacy policy describes.

8. Disclaimers

To the extent the law allows, MyOnCall is provided "as is", without warranties of any kind, express or implied.

9. Limitation of liability

To the extent the law allows, we aren't liable for indirect or consequential losses, such as lost profits, lost data or losses from missed incidents. Our total liability for any claim is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that can't be limited by law.

10. Changes to these terms

We may update these terms. We'll change the date at the top, and for significant changes we'll tell workspace owners in Slack at least 30 days before they take effect. If you keep using MyOnCall after that, the new terms apply.

11. Governing law

These terms are governed by the laws of Brazil. Disputes go to the courts of the city where FONTANA & SYDOW SERVICOS EM TECNOLOGIA LTDA has its registered office, in Brazil, unless the law gives you the right to bring them elsewhere.
