YETLYUPDATED 21 AUG 2026

Terms of Use

These terms are the agreement between you and me about the Yetly app. They also serve as Yetly’s End User License Agreement (EULA).

The short version

Yetly is a small app made by one person. You can use it on the Apple devices you own. It is free, all of it, with nothing to buy inside it and no subscription. Your data stays on your device, so there is very little here that can go wrong between us, and the rest of this page is the careful wording for the parts that can.

1. Who you are agreeing with

Yetly is made and licensed by Sepehr Mohammadi (“I”, “me”, “the developer”).

This agreement is between you and me only, and not with Apple. I, not Apple, am solely responsible for Yetly and its content. Apple distributes Yetly, and Apple is not a party to these terms.

By downloading or using Yetly, you agree to these terms. If you do not agree, please do not use the app, and you can delete it.

2. Your license

I grant you a personal, non-exclusive, non-transferable, revocable license to use Yetly on any Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. That includes access by other members of your Family Sharing group where Apple’s rules allow it.

This license covers use of the app, not ownership of it. You may not:

  • copy, redistribute, sell, rent, sublicense, or lease the app
  • reverse engineer, decompile, or disassemble it, except where law says you may
  • remove or obscure any copyright, attribution, or other notice in it
  • use it in a way that breaks the law where you are

The app, its name, its design, and its code stay mine. The things you put into Yetly stay yours, entirely, and I never see them.

3. What Yetly costs

Nothing. Yetly is free, in full. Every part of the app is included: adding, editing, completing, undoing, and removing as many things as you like, one gentle reminder per thing at a time you choose, the Done and Not yet buttons on that reminder, notes on every thing, search, the Apple Watch app and its complications, every home-screen and lock-screen widget, rhythm suggestions, exporting and restoring a backup, and light and dark themes.

  • There are no in-app purchases, no subscription, no trial, no unlock, and no paid tier. Nothing in the app is held back from you.
  • There are no ads, no sponsored content, and no analytics.
  • Your data is never held hostage. Export and restore are always there. You can take your things out of Yetly at any time.

Because there is nothing to buy, there is nothing to refund. If you ever have a billing question about the App Store itself, that is Apple’s to answer, at reportaproblem.apple.com.

4. Maintenance and support

I am solely responsible for providing any maintenance and support services for Yetly, to the extent those services are specified in these terms or required under applicable law. Apple has no obligation whatsoever to furnish any maintenance and support services with respect to Yetly.

In practice, support is one email address, read by one person: [email protected]. See the support page for what to expect. I try to answer everything, usually within a few days, and I cannot promise a response time or guarantee that any particular fix or feature will be built.

5. No warranty

Yetly is provided “as is” and “as available”, without warranty of any kind. To the maximum extent permitted by applicable law, I disclaim all warranties, express or implied, including the implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. I do not warrant that Yetly will be uninterrupted, error free, or free of defects, or that it will work with every future version of iOS or watchOS.

Please read this part in particular:

Yetly is a gentle memory aid, not a guarantee. Reminders are scheduled as local notifications and are delivered by iOS, which may delay or suppress them for reasons outside the app, such as Focus modes, Low Power Mode, notification settings, a device that is off, or a permission you did not grant. Do not rely on Yetly alone for anything where a missed reminder matters, and in particular do not rely on it for medication, medical treatment, safety equipment, legal deadlines, or financial obligations. Use a tool built for those purposes.

You are responsible for your own backups. Your things live only on your device. Yetly does not sync and has no cloud copy, so a lost, wiped, or broken device means lost data unless you have exported a backup or kept a device backup. Settings has an Export a backup row for exactly this reason.

In the event of any failure of Yetly to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for Yetly to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to Yetly. Any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to any warranty are my responsibility, not Apple’s.

Some jurisdictions do not allow the exclusion of certain warranties, so parts of this section may not apply to you, and nothing here limits any statutory consumer right you have that cannot be waived.

6. Limitation of liability

To the maximum extent permitted by applicable law, I am not liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, loss of profits, loss of goodwill, or business interruption, arising out of or relating to your use of Yetly, however caused and on any theory of liability.

To the maximum extent permitted by applicable law, my total liability to you for all claims relating to Yetly is limited to the greater of the amount you actually paid for Yetly in the twelve months before the claim, or five US dollars.

These limits do not apply to liability that cannot be excluded or limited by law, such as liability for death or personal injury caused by negligence, or for fraud or fraudulent misrepresentation. Some jurisdictions do not allow the limits above, so they may not apply to you in full.

7. Product claims

I, not Apple, am responsible for addressing any claims by you or any third party relating to Yetly or your possession or use of it, including product liability claims, any claim that Yetly fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation, including in connection with Yetly’s use of any framework that processes health or fitness data (Yetly does not use any such framework).

These terms do not limit my liability to you beyond what applicable law permits.

8. Intellectual property claims

If any third party claims that Yetly, or your possession and use of Yetly, infringes that third party’s intellectual property rights, I, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of that claim.

You represent and warrant that:

  • you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and
  • you are not listed on any U.S. Government list of prohibited or restricted parties.

You agree to comply with all applicable U.S. and other export laws and regulations, and with all applicable local laws where you use Yetly. Yetly implements no cryptography of its own and makes no network requests.

10. Third-party terms

You must comply with any applicable third-party terms of agreement when using Yetly. That includes the Apple Media Services Terms and Conditions and, if you choose to save an exported backup into another service such as a cloud storage app, that service’s own terms.

11. Apple as a third-party beneficiary

Apple, and Apple’s subsidiaries, are third-party beneficiaries of these terms, and upon your acceptance of these terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these terms against you as a third-party beneficiary of them.

Apple is otherwise not a party to these terms, has no responsibility for Yetly, and, as stated above, has no maintenance, support, or warranty obligation with respect to Yetly.

12. Acceptable use

Yetly is a private list on your own device, so there is not much to police here. Still, please:

  • use Yetly only for lawful purposes
  • do not use a modified or repackaged copy of the app
  • do not attempt to interfere with the app’s operation on someone else’s device
  • do not use Yetly’s name, icon, or design to represent something that is not Yetly

There is no content moderation, because nothing you write in Yetly is ever shared or sent anywhere. What you type is yours and stays on your device.

13. Changes to these terms

I may update these terms, for example if Yetly gains a feature that needs covering. The “Last updated” date at the top changes when they do, and the current version is always the one linked from Yetly’s App Store page.

If a change is significant, the app will tell you the next time you open it. Your continued use of Yetly after an update means the updated terms apply. If you do not agree with an update, you can stop using Yetly and delete it, and you can export your things first.

14. Termination

This license lasts until it ends. It ends when you delete Yetly from all your devices, or if you materially breach these terms, in which case the license terminates automatically. On termination you must stop using Yetly and delete it. Sections 7 through 13 survive termination. Deleting the app does not entitle you to a refund, though Apple’s refund process remains open to you under Apple’s policies.

15. Governing law

These terms are governed by the laws of the Netherlands, without regard to its conflict of law rules, and you and I agree to the exclusive jurisdiction of the courts located in the Netherlands for any dispute arising out of them.

If you are a consumer, this does not deprive you of the protection of the mandatory consumer laws of the country where you live, and it does not remove your right to bring proceedings in your local courts where the law gives you that right.

16. Everything else

  • Entire agreement. These terms, together with the Privacy Policy, are the whole agreement between you and me about Yetly, and they replace any earlier understanding about it.
  • Severability. If any part of these terms is held unenforceable, the rest stays in force and the unenforceable part is applied only as far as the law allows.
  • No waiver. If I do not enforce a part of these terms straight away, I have not given it up.
  • Assignment. You may not assign these terms. I may assign them if Yetly changes hands, and your license carries over.
  • Language. These terms are written in English. If a translation is provided and it conflicts with the English, the English version governs, except where local law says otherwise.

17. Contact

Sepehr Mohammadi Box C8724, Keurenplein 41, 1069 CD Amsterdam, Netherlands [email protected]

That address and email are here because Apple’s minimum EULA terms require a developer name, address, and contact information. The email is the one that gets read.
