The short version: your GLP-1 record — shots, weight, side effects, lifestyle — never leaves your phone. RenewLog has no account, no cloud and no ads, and we never see your health information.
No health information, ever. RenewLog has no accounts, no analytics, no ads and no tracking of any kind. Your doses, weight entries, side effects, lifestyle log and the optional name, date of birth and height you add exist only on your device. The only network request is the purchase check described under Third parties (store receipt and an anonymous app ID). We never receive, store or sell any health information.
Everything you enter is stored locally on your device, not on any server of ours. It leaves your phone only when YOU export it (the Renewal Packet PDF, a CSV or a backup file) and share it yourself — with your doctor, your insurer or anyone you choose. Like any app data, it can also be included in your phone's own system backup if you have that turned on.
Your entries are never sent to anyone. On iPhone and Android, RenewLog includes one third-party SDK, RevenueCat, used only to validate the optional one-time unlock ($9.99 after the free trial). The purchase itself is processed by Apple or Google Play; RevenueCat receives the purchase receipt, an anonymous app user ID and a device identifier. It never receives your shots, weights, notes, name, date of birth or any health information, and none of this is used for tracking or advertising.
Apple App Store: "Data Not Linked to You" — Purchases (purchase history) and Identifiers (anonymous user ID, device ID), used only for app functionality and never for tracking. Google Play Data safety: purchase history and device or other IDs, collected only for app functionality (the unlock), not shared and never used for tracking. Health information never leaves the device.
Your data is yours. Use "Delete all my data" in Settings (or simply delete the app) and everything is gone permanently. Export it any time from Settings or the Packet tab.
RenewLog is a personal logbook. It does not provide medical advice, diagnosis or treatment, and it cannot promise any insurance outcome. Always talk to your healthcare provider.
