LockNotes

Terms of Use

Last updated: 27 July 2026 · Effective: 27 July 2026

These Terms of Use (“Terms”) are a legal agreement between you and Ratera Yazılım ve Bilişim A.Ş. (“LockNotes”, “we”, “us”) governing your use of the LockNotes iOS application and related services (the “App”). By downloading or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. License

We grant you a limited, non-exclusive, non-transferable, revocable license to use the App on Apple-branded devices that you own or control, for your personal, non-commercial use, in accordance with these Terms and the Apple App Store Terms of Service. This license is the Licensed Application End User License Agreement for the App (see §11).

2. Subscriptions & billing

LockNotes may offer auto-renewable subscriptions and one-time (non-consumable) purchases such as a lifetime offer. Prices, billing period, and features are shown in the App before you buy.
Payment is charged to your Apple ID at confirmation of purchase.
An auto-renewable subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Your Apple ID is charged for renewal within 24 hours before the period ends.
You manage or cancel subscriptions in Settings › [your Apple ID] › Subscriptions. Deleting the App does not cancel a subscription.
Except where required by law, payments are non-refundable; refunds are handled by Apple under the App Store terms.
Any unused portion of a free trial is forfeited when you purchase a subscription.

3. Shared notes & your content

LockNotes lets you share a note with other people using an invite code or QR code. When you use sharing:

You own your content. You retain all rights to the notes, todos, doodles, and photos you create. You grant us only the limited license needed to host, transmit, and display that content to the people you shared it with — solely to operate the service, and for nothing else.
Sharing is real. Everyone in a shared note can view and edit it, its content appears on their lock screens, and their devices keep local copies that may persist after you stop sharing. Share only what you are comfortable with others seeing and keeping.
Invite codes are keys. Anyone you give a valid invite code or QR code to can join the note. You are responsible for who you hand them to.
Your responsibility. You are responsible for the content you create and share. Do not share content that is unlawful, infringing, harassing, or that you do not have the right to share. We may suspend access or remove shares that violate these Terms or the law.

4. Acceptable use

You agree not to: reverse engineer, decompile, or tamper with the App except as permitted by law; use the App unlawfully or to harass, harm, or deceive others; attempt to access shared notes you were not invited to; interfere with the App's security or operation; or use it in any way that violates Apple's or our providers' terms.

5. Intellectual property

The App, including its design, text, graphics, and software, is owned by LockNotes and its licensors and is protected by intellectual-property laws. Except for the license in §1, no rights are granted to you. Your content remains yours as described in §3.

6. Third-party services & lock-screen features

The App relies on third-party services including Apple (push notifications, Live Activities, StoreKit), Google Firebase, RevenueCat, and Superwall. Your use of those services may be subject to their own terms, and we are not responsible for third-party services.

Lock-screen delivery is best-effort. Live Activities, widgets, and push updates are operated by Apple and iOS, and their delivery, timing, and visibility are outside our control — iOS may delay, throttle, or end them (for example after a restart, in Low Power Mode, or when the app is force-quit). Do not rely on LockNotes as your only reminder for anything critical, such as medication, deadlines, or safety-related tasks.

7. Disclaimer of warranties

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. We do not warrant that the App, syncing, or lock-screen updates will be accurate, timely, uninterrupted, or error-free. You use the App at your own risk.

8. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LOCKNOTES AND ITS SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, MISSED REMINDERS, OR LOSS ARISING FROM CONTENT SHARED BY YOU OR OTHER USERS. Our total liability for any claim relating to the App will not exceed the amount you paid for the App in the 12 months before the claim. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

9. Termination

These Terms apply until terminated. Your license ends automatically if you breach them. You may end them by deleting the App. Sections that by their nature should survive (e.g. §§3, 5, 7, 8, 10) survive termination.

10. Governing law

These Terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-laws rules, except where mandatory consumer-protection laws of your country of residence apply. This does not limit Apple's role as described in §11.

11. Apple App Store — required terms

The following apply because the App is distributed through the Apple App Store:

These Terms are between you and LockNotes only, not with Apple. Apple is not responsible for the App or its content.
Apple has no obligation to provide maintenance or support for the App.
If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any). To the maximum extent permitted by law, Apple has no other warranty obligation, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a failure to conform to a warranty are LockNotes's responsibility.
Apple is not responsible for addressing any claims by you or a third party relating to the App or your use of it, including product-liability, legal/regulatory, or consumer-protection claims.
For third-party intellectual-property infringement claims relating to the App, LockNotes, not Apple, is responsible for investigation, defense, settlement, and discharge.
You represent that you are not located in a country subject to a U.S. Government embargo or designated a “terrorist-supporting” country, and are not on any U.S. Government list of prohibited or restricted parties.
Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

12. Changes

We may update these Terms. Material changes take effect when we post the updated Terms and update the “Last updated” date. Continued use after changes means you accept them.
