Daystone — Terms of Use
Effective date: October 3, 2026
These Terms of Use (the "Terms") govern your use of the Daystone mobile application ("Daystone" or the "App") provided by SMJY Tech ("we" or "us"). By downloading or using the App, you agree to these Terms. If you do not agree, please do not use the App.
Contents
1. License to use the App
Subject to your compliance with these Terms, we grant you a personal, non-exclusive, non-transferable, revocable licence to download, install and use the App on a device that you own or control, for your own personal, non-commercial use.
2. The service
Daystone is a fully offline countdown and anniversary app. It counts days to or from the dates you enter, lets you organise them with icons, types, repetition and pins, and can schedule local morning-of reminders. Everything runs on your device; the App has no server component. Dates and counts are provided for informational purposes only.
3. Reminders
Reminders are delivered by your device's local notification system and depend on the notification permission you grant. The App indicates plainly whether a reminder will fire; if the permission is missing or revoked by the operating system, reminders may not be delivered. We have no way to send reminders outside your device and cannot guarantee delivery on any particular schedule.
4. Your responsibilities
You agree to use the App lawfully and not to misuse, reverse-engineer, redistribute or attempt to disrupt it. You are responsible for the dates you enter and for verifying that a countdown matters before you rely on it. The App is a personal memory aid, not a certified scheduling, medical or legal instrument.
5. Your data and backups
All data lives on your device. The App provides an export to a single file and a restore that accepts only Daystone's own format, but keeping safe backups is your responsibility. Uninstalling the App deletes your local data; we cannot recover it for you because we never had it.
6. Intellectual property
The App, its name, its design and its content are owned by SMJY Tech and protected by applicable intellectual-property laws. These Terms do not grant you any right to use our trademarks or to copy or redistribute the App beyond the personal licence in section 1.
7. Disclaimer of warranties
The App is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties, whether express or implied, including any warranty of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that reminders will always be delivered or that the App will be uninterrupted or error-free.
8. Limitation of liability
To the maximum extent permitted by law, in no event shall SMJY Tech be liable for any indirect, incidental, special or consequential damages — including a missed event or date — or for any loss of data, arising out of or in connection with your use of the App. Because the App is provided free of charge, our aggregate liability is limited to the amount, if any, you have paid us for the App in the preceding twelve months.
9. Changes to the App and to these Terms
We may update, modify or discontinue features of the App, and we may revise these Terms from time to time. The "Effective date" above reflects the latest version of the Terms. Continued use of the App after a change constitutes acceptance of the revised Terms.
10. Contact and governing terms
For installs from Apple's App Store, Apple's standard End User Licence Agreement (EULA) applies where applicable; for installs from Google Play, the Google Play Terms of Service apply. Each applies together with these Terms. For any question about these Terms or the App, contact us at tzhh0617@gmail.com.
