The short version
Yetly keeps your things on your phone and nowhere else. There is no account to make, no server to sign in to, and nothing about you is ever sent anywhere, because Yetly makes no network requests at all. It has no analytics, no crash reporting, no tracking, and no advertising. If you delete the app, your things go with it, and that is the whole story.
The sections below say the same thing in the more careful language a store listing and a reviewer expect.
1. Who this policy is from
Yetly is made by Sepehr Mohammadi, an independent developer. You can reach me at [email protected].
This policy covers the Yetly iPhone app, the Yetly Apple Watch app, and their home-screen, lock-screen, and watch-face widgets. They are one product and they share the same on-device storage.
2. What Yetly collects
Nothing.
Yetly does not collect, transmit, sell, share, or receive any personal information. To be specific, Yetly does not collect:
- your name, email address, phone number, or any other contact detail
- any account, login, or user identifier (there are no accounts)
- your location, at any level of precision
- your contacts, calendars, photos, health data, or microphone or camera input
- your device identifiers, advertising identifier, or IP address
- usage analytics, session data, screen views, taps, or feature usage
- crash reports or diagnostic logs
- any identifier used for tracking you across apps or websites
Yetly asks for exactly one system permission: permission to send you notifications. You are asked during the first-run intro, you can say no, and the app works without it. Nothing about that choice leaves your device.
There is no field anywhere in Yetly that asks who you are.
3. Yetly makes no network requests
Yetly contains no networking code. It does not open connections, does not call any web service, and does not contact me or anyone else. There is no server behind Yetly to contact.
Yetly also contains no third-party software development kits (SDKs) of any kind. There is no analytics library, no crash reporter, no advertising or attribution framework, and no remote configuration service. The shared logic package the apps are built on declares zero external dependencies.
One consequence worth stating plainly: because there is no network layer, there is no path by which your data could leave your device, even by mistake.
4. What is stored on your device
Everything Yetly knows lives in your device’s own storage, inside the app’s sandbox, protected by iOS. Specifically:
Your things. A single JSON file holding the things you track. For each one: the name you typed, the icon, how often it repeats, when you last marked it done, when you created it, your optional note, and a bounded log of your most recent completion dates (the last 24, used only to offer a gentler rhythm suggestion). This file lives in a shared app-group container (group.app.yetly.shared) so that the watch app and the widgets can read the same data as the iPhone app. On older installs it may still live in the app’s own Application Support directory, which Yetly copies forward once.
Your preferences. Small settings in UserDefaults: whether reminders are on, the time of day you picked, whether you want light or dark, whether little haptics are on, whether you have seen the intro, and the “not yet” dates for anything you have gently pushed back. Some of these sit in the same shared app-group suite so the widgets behave the same way the app does.
Your reminders. When reminders are on, Yetly schedules local notifications with iOS (UNUserNotificationCenter). A scheduled reminder includes the name of the thing, so that name can appear on your lock screen. iOS holds these notifications; they are never sent through any server, and they are removed and rebuilt on your device whenever your things change.
That is the complete list. Yetly writes nothing else.
5. Backups you make yourself
Yetly can export a backup of your things as a JSON file, and can restore one you pick.
- Export writes the file into the app’s temporary folder and hands it to the standard iOS share sheet. Where it goes next is entirely your choice: Files, AirDrop, a message to yourself, iCloud Drive, wherever. Yetly does not upload it and does not know where you put it. If you choose a destination that syncs to a cloud service, that service’s own privacy policy applies to the copy you put there.
- Restore reads only the one file you pick in the system file picker. Yetly cannot browse your files and never looks at anything you did not choose. A restore only adds and updates; it never deletes what is already there.
6. iCloud sync
Yetly does not sync across devices, and this version has no iCloud integration. Your iPhone and your Apple Watch share data because they are one app on paired hardware, not because anything travels through a cloud.
Syncing across your own devices with iCloud is something I would like to build one day. It does not exist yet. If it ever ships, this policy will be updated before it does, and it will be described honestly here.
7. Third parties
There is exactly one, and it is Apple.
Apple, as the App Store. You get Yetly from the App Store, so Apple handles your download and your updates. Apple’s own privacy policy covers everything that happens in that relationship, and it is separate from this one. See Apple’s Privacy Policy. Yetly is free and sells nothing, so there is no payment in that relationship at all.
Apple, for aggregate reports. If you have turned on sharing analytics or diagnostics with developers in your iOS settings, Apple may show me anonymous, aggregated reports (install counts, crash counts, and similar) in App Store Connect. That is an Apple feature, controlled by you in iOS Settings, not something Yetly does. Yetly contains no analytics or crash-reporting code, and those reports do not identify you and never contain your things.
Bundled open data. Yetly’s icon picker searches an emoji keyword list built from Unicode CLDR annotation data (via the emojibase project) and licensed for this use. It is a static file compiled into the app, it is read offline, and it sends nothing anywhere. Attribution is in the app’s Settings and in the repo’s NOTICE file.
Nobody else is involved. There are no advertisers, no data brokers, no processors, and no partners.
8. Children
Yetly is suitable for all ages, and there is no age gate, because there is nothing to gate. The app collects no data from anyone, of any age.
Yetly is not directed to children under 13 for the purpose of collecting personal information, and it does not knowingly collect personal information from children under 13, or from anyone else. There is no sign-up, no profile, no messaging, no user-generated content shared with anyone, no advertising, and no third-party tracking. Since no data is collected, there is nothing for a parent or guardian to review, correct, or ask me to delete. If you have a question about this anyway, please write to me at [email protected].
9. Data retention and deletion
I retain nothing, because I receive nothing. There is no database anywhere with your things in it.
Your data lives on your device for exactly as long as you want it to. You are in control of all of it:
- Remove one thing. Long-press it on the home list and choose Remove. There is a short window to undo, then it is gone.
- Start fresh. Settings has a Start fresh row that clears everything from this device. It asks once, and it cannot be undone.
- Delete the app. Deleting Yetly removes its containers, which removes your things, your preferences, and any reminders it had scheduled. Nothing survives it on my side, because nothing was ever on my side.
- Keep a copy first if you want one. Settings can export a backup before you clear or delete, and Restore brings it back later.
One honest note: if you have exported a backup and saved it somewhere yourself, that copy is yours to look after. Deleting the app does not reach into wherever you put it.
10. Your rights
Privacy laws in many places, including the EU and UK GDPR and the California Consumer Privacy Act, give you rights to access, correct, port, and delete the personal data a company holds about you, and to know whether it is sold or shared.
Yetly’s answer to all of them is the same. I hold no personal data about you, so there is nothing to access, correct, port, or delete, and nothing that could be sold or shared. Yetly does not sell or share personal information, and it does not process it for targeted advertising or profiling.
You can exercise all of these yourself, immediately, without asking me: your data is on your device, you can read it (export a backup and open the JSON), change it, or delete it, any time. If you would like to ask me a question about this anyway, you are welcome to.
11. International users
Yetly is available in the App Store storefronts Apple offers, and it works the same everywhere.
Because your data never leaves your device, Yetly performs no international transfer of personal data. There is no cross-border flow to disclose, no standard contractual clauses to point at, and no processor in another country. Whatever country you are in, your things stay on the phone in your hand.
Apple’s handling of your App Store account and your download may involve Apple’s own infrastructure and transfers, which are covered by Apple’s Privacy Policy, not by this one.
12. Security
Your things sit inside the app’s sandbox on your device, covered by iOS’s own file protections and by your device passcode, Face ID, or Touch ID. Keeping your device locked and up to date is the best protection there is, and it is more than any server-side promise could offer.
Because Yetly holds nothing on a server, there is no server-side breach that could expose your data.
13. Changes to this policy
If Yetly ever changes what it does with data, this policy changes first, and the “Last updated” date at the top changes with it. Any new version is posted at the privacy policy link on Yetly’s App Store page.
Two promises about how that will go. If a future version of Yetly ever collects or transmits anything, I will say so plainly here and in the release notes, and I will not make a change like that quietly. And if a change is significant, the app itself will tell you the next time you open it, rather than leaving it to you to notice.
Your continued use of Yetly after an update means the current version of this policy applies.
