App terms · effective 25 September 2026
Clear terms for using Centile.
On iPhone, Centile is licensed through Apple under Apple’s Standard EULA. On Android, Centile is distributed through Google Play. This page records the product, safety, privacy and subscription information that applies alongside them.
1. Product and eligibility
Centile provides educational height estimates, local measurement tracking and optional general-wellbeing guidance. It is intended for people aged 13 or older and for parents or guardians using it for or with a teenager.
2. Estimates, not guarantees
Free and Plus estimates are estimates with stated uncertainty. They do not guarantee final height, diagnose a condition, recommend treatment or replace a qualified health professional.
Healthy-habit completion never changes predicted height and must not be interpreted as a growth, health or compliance score.
3. Safe use
Use the in-app guidance and stop conditions. Take growth, health, pain, dizziness, breathing, injury or emergency concerns to an appropriate qualified professional or emergency service. Centile is not an emergency or medical service.
4. Free use and subscriptions
The adult height estimate remains free. On iPhone, a Centile Plus offer shows Apple’s local billed price, billing period, renewal treatment and included features before purchase. Subscriptions renew automatically unless cancelled.
On iPhone, Apple handles payment, subscription management and refund requests. You can manage a subscription or request a refund from Apple.
On Android, Google handles payment, subscription management and refunds under Google Play’s terms. You can manage a subscription in Google Play or ask Google Play for a refund.
Deleting local app data does not cancel an Apple or Google Play subscription. Cancelling a subscription does not delete local app data. Restore affects eligible entitlement, not the local profile or measurements.
5. Local data and privacy
The privacy notice explains the local-data, device-sharing, backup and deletion boundaries. SLT Workshop Limited cannot access, restore, correct or delete the on-device profile remotely.
6. Availability and changes
Features may change to correct errors, maintain compatibility, improve safety or meet platform and legal requirements. Availability can vary by device, iOS or Android version, Apple or Google Play storefront, or territory. The website and app may occasionally be unavailable.
7. Consumer rights and contact
Apple’s Standard EULA governs the iPhone app licence. Your local consumer rights continue to apply where the law requires them. For product, privacy or security questions, contact SLT Workshop Limited at support@centile.app.
