JC Timegrapher is built to respect your privacy. Your watches and measurements stay on your device. The free version shows ads, which involve the limited data sharing described below; JC Timegrapher Pro removes ads entirely. This policy explains what the app does with your information.
Nothing about you. JC Timegrapher has no accounts, no logins, and no analytics of its own. We never see your watches or your measurements.
The free version displays ads through Google AdMob. To serve ads, Google may collect and process information such as your device's advertising identifier, IP address, and general usage and diagnostic data. This information is shared with Google as a third party and is handled under Google's Privacy Policy (policies.google.com/privacy).
On first launch, iOS asks whether JC Timegrapher may track you (App Tracking Transparency). You can decline and keep using every feature — you will simply see less-personalized ads.
Purchasing JC Timegrapher Pro removes all ads and their associated data sharing. Purchases are processed by Apple; we never receive your name or payment details.
JC Timegrapher uses the microphone only to listen to your watch while you are actively measuring. Audio is analyzed in real time on your device and is never recorded, saved, or transmitted. You can grant or revoke microphone access at any time in Settings › Privacy & Security › Microphone.
Your watches, measurements, service records, and photos are stored only on your device (and in your own device or iCloud backups, if you use them). They are never sent to us, and we have no access to them. To delete this data, delete the item within the app or remove the app from your device.
JC Timegrapher is not directed to children and does not knowingly collect personal information from children.
If this policy changes, we will update this page and revise the "Last updated" date above.
