Terms of Use

Last updated: 21 September 2026

These Terms of Use (“Terms”) govern your use of the Kati mobile application (“Kati”, “the app”). By downloading or using Kati, you agree to these Terms. If you do not agree, do not use the app.

What Kati is

Kati is an offline-first child immunization record-keeping aid built around Nigeria’s national schedule. It helps you keep track of doses you enter. It is not medical advice, does not diagnose or treat any condition, and does not tell you whether to vaccinate. Always follow guidance from a qualified health worker or clinic.

Your records

Child profiles and dose records you enter are stored on your device. You are responsible for the accuracy of information you enter and for keeping backups if you choose to export or share them.

Kati Plus subscriptions

Optional paid features are offered as Kati Plus auto-renewable subscriptions and/or a lifetime purchase through the Apple App Store (for example Monthly, Yearly, or Lifetime), as shown at the time of purchase.

• Service: Kati Plus unlocks paid features in the app as described on the purchase screen.
• Length and price: Subscription length and price are displayed in the app and on the App Store product / purchase sheet before you confirm. Prices may vary by region and are set in App Store Connect.
• Payment will be charged to your Apple ID account at confirmation of purchase.
• Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period.
• Your account will be charged for renewal within 24 hours prior to the end of the current period, at the rate shown for that subscription.
• You can manage subscriptions and turn off auto-renewal in your Apple ID Account Settings after purchase (Settings → Apple ID → Subscriptions), or as otherwise provided by Apple.
• Any unused portion of a free trial period, if offered, is forfeited when you purchase a subscription where applicable under Apple’s rules.

Purchases are processed by Apple. Kati does not receive your payment card details. Purchase status may be checked with Apple and RevenueCat so the app can unlock Kati Plus features.

Privacy

Our Privacy Policy explains what stays on your device and how purchases are handled. By using Kati you also acknowledge that policy.

Acceptable use

Use Kati only for lawful personal record-keeping. Do not misuse the app, attempt to interfere with its operation, or use it to provide clinical care or medical advice to others as a substitute for a qualified professional.

Disclaimer of warranties

Kati is provided “as is” and “as available.” To the fullest extent permitted by law, we disclaim warranties of merchantability, fitness for a particular purpose, and non-infringement. Schedule information is intended as a convenience for record-keeping and may not reflect every clinic’s practice.

Limitation of liability

To the fullest extent permitted by law, Kati and its contributors are not liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising from your use of the app. Your sole remedy for dissatisfaction with Kati is to stop using it and, where applicable, manage or cancel your subscription through Apple.

Changes

We may update these Terms from time to time. The “Last updated” date above will change when we do. Continued use of Kati after an update means you accept the revised Terms.
