Privacy
The short version: what you type into Nag stays on your iPhone. There are no accounts, no ads and no tracking. The app sends a few anonymous counts so we can tell which parts work.
Last updated 20 October 2026
Who we are
Nag is made by Jorge Plaza, an independent developer, who is responsible for the data described here. For anything about your privacy, email support@usenag.com.
What stays on your device
Your tasks, their deadlines, who you handed them to, and your settings are saved on your iPhone only. Reminders are scheduled by iOS on the phone itself. None of it is sent to us, and we couldn’t read it if we wanted to.
Deleting the app deletes all of it. If you back up your iPhone to iCloud or a computer, Apple includes it in that backup, under Apple’s terms.
Anonymous usage counts
To see what’s working, Nag uses TelemetryDeck, an analytics service built not to identify people. The app sends a short signal when certain things happen:
- a step of the first-run setup is shown, skipped or finished, and whether notifications were allowed
- a task is handed over, ticked off or un-ticked, with which character and mode were used, how often they ping, and how long the task stayed open
- a reminder is opened
- the unlock screen is shown, the unlock is bought or restored, or a code is redeemed. For a purchase this includes the price, currency and App Store country
Each signal also carries basic technical details: the app and iOS version, the device model, language and region settings, and display settings such as dark mode or text size.
The text of your tasks is never sent. Nor is your name, email, contacts, location or anything else that says who you are.
To count returning users without knowing who they are, the app sends a random device identifier that is scrambled (hashed) before it leaves the phone, so it can’t be traced back to you or matched with data from other apps. TelemetryDeck doesn’t store IP addresses, and keeps its data on servers in the EU.
We rely on our legitimate interest in improving the app for this. If you’d rather not take part, deleting the app stops it.
Purchases
The unlock and any codes are handled by Apple through the App Store. We never see your payment details or your Apple Account. Apple tells the app only whether you’ve unlocked it.
Checking the price
To know whether the launch price is still on, the app downloads a small file from usenag.com, at most once an hour while it’s open. Nothing about you or your tasks is sent with it. As with any website, Cloudflare, which hosts usenag.com, sees your IP address in order to send the file back. We don’t keep logs of these requests.
What we don’t do
- No accounts or sign-in
- No advertising, and no ad or tracking SDKs
- No selling or sharing of data with anyone, for any reason
- No tracking across other apps and websites
Nag Plus, later
Nag Plus, an optional subscription that isn’t out yet, will write each reminder with AI. To do that it will need to send a task’s text to a server. It will be off unless you turn it on, and this policy will be updated to say exactly what is sent and where, before it launches.
This website
This site sets no cookies and runs no analytics. It’s hosted by Cloudflare, which processes basic request data, such as IP addresses, to serve the pages and keep them secure.
Your rights
Wherever you live, you can ask what data about you we hold, and ask for it to be corrected or deleted. Because the usage counts are anonymous, we usually can’t link any of them to you, but we’ll help however we can. If you’re in the EU or UK you can also complain to your data protection authority, in Spain the AEPD.
Children
Nag isn’t made for children under 13, and hound mode is full of swearing. We don’t knowingly collect anything from children.
Changes
If this policy changes, the new version will be posted here with a new date.
