Terms of Service

These terms cover your use of InjectBuddy and its optional paid subscription. They are written in plain wording. By using the site or the app you agree to them.

Using InjectBuddy

The calculators are free and need no account. InjectBuddy is a maths tool, not medical advice. Please read the disclaimer before relying on any result.

Subscriptions

Some features are part of an optional paid plan. You can buy it on the web (checkout and billing handled by Stripe) or in the app through the App Store or Google Play. Your subscription unlocks the paid features on every device you sign in on with the same account.

Free trial

A new subscription starts with a 7-day free trial. If you do not cancel before the trial ends, it converts to the paid plan and you are charged the price shown at checkout. If you cancel before the trial ends, you are not charged.

Renewal and cancelling

After the trial, your subscription renews automatically each period until you cancel. You can cancel at any time:

Cancelling in one place does not cancel a subscription bought in the other. When you cancel, you keep the paid features until the end of the period you have already paid for.

Refunds

Purchases made through the App Store or Google Play are refunded under Apple’s or Google’s policy, so please ask them. Web purchases follow the terms shown at Stripe checkout; if you need help, contact us.

Prices and currency

InjectBuddy is available worldwide. The price is shown in your local currency at checkout, and your store or card issuer may add taxes or conversion fees.

Price changes

If the price changes, we will give you notice before the new price applies to your renewal, so you can cancel first if you do not want to continue.

Contact

If you have questions about these terms, contact the InjectBuddy team via the About page. See also our Privacy Policy.
