In short: Calcrete is built local-first. Your data stays on your device. There is no account to create, we do not run ads or third-party analytics, and we never sell your data.
This policy explains how Calcrete ("we", "us") handles information. Calcrete is provided by Jade Clear.
Everything you enter is stored locally on your device. We have no server that receives or stores this content, and we cannot see it. If you use Apple's device/iCloud backup, a copy may be included under your own Apple account and Apple's terms — controlled by you and Apple, not us.
Payments are processed by Apple; we never receive your card or payment details. We use RevenueCat to validate and restore purchases, processing a random app user id + purchase history needed for entitlement and fraud prevention — not for tracking or advertising. See RevenueCat and Apple privacy policies.
You control your data on-device; deleting the app removes its local data. Questions or requests: shq.shenhuaqing@gmail.com.
Calcrete is intended for adults and not directed to children; we do not knowingly collect data from children.
We may update this policy; material changes update the "Last updated" date above.
