Terms of Use

1. Parties and acceptance

These Terms govern the relationship between the user (“you”) and Serkan Aktaş (“Publisher”), provider of the Shift Sleep Planner mobile application and related services (“App”). Contact: serqanaktas@gmail.com. By continuing to use the App, you accept these Terms. If you do not agree, stop using the App and remove it from your device.

You represent that you are legally permitted to use the App and enter into these Terms where you live. The App is not directed to children.

2. What the App provides

The App may provide shift and calendar planning, repeating shift patterns, shift/sleep records, sleep-window and rest-opportunity calculations, statistics and summaries, reminders, home-screen widgets, tools, backup, and file/calendar import and export. Features may vary by device, operating system, language, store availability, and subscription status.

App outputs depend on the times and preferences you enter. You are responsible for checking schedule accuracy, time zones, and imported files. Keep tokenized calendar-feed URLs confidential. Backups and shared files may contain sensitive work and sleep records; share them only with destinations you trust.

3. Important health, safety, and fitness-for-work limitations

The App is a general information and personal planning tool only. It is not a medical device, sleep-measurement tool, diagnosis, treatment, clinical advice, emergency service, fatigue assessment, or fitness-for-work determination. The App does not measure whether you are asleep; it works with plans and records you enter.

Sleep opportunities, sleep-cycle times, caffeine estimates, rest intervals, scores, chronotype results, and other suggested information are not personal or professional advice. Outputs may be inaccurate, incomplete, interrupted, or unsuitable for your circumstances. They do not replace workplace rules, legal requirements, or employer procedures. Do not rely on an App calculation for a safety-critical decision.

For questions about sleep, health, medication, caffeine, or work safety, consult a qualified health professional and follow your employer's or safety officer's directions. Do not interact with the device while driving or doing hazardous work. If you feel sleepy or unsafe, stop the activity and seek safe assistance regardless of the App's plan.

4. Your responsibilities and acceptable use

• Enter accurate, current shift and sleep details, and evaluate any calculations against your own circumstances.
• Use the App in compliance with applicable law, workplace rules, and third-party rights.
• Do not reverse-engineer the App, bypass security, disrupt the service, or use it for unlawful purposes.
• Protect backup files, calendar-feed URLs, and device access; consider privacy when using the App on a shared device.

You retain rights to information you enter. You grant the Publisher a limited right to process it as needed to provide the App functions you request. The Publisher does not claim ownership of your in-app records.

5. Pro features, subscriptions, and store transactions

Some features may be paid. The package, price, currency, trial period, billing period, automatic-renewal, and cancellation details will be shown in the purchase screen and relevant store before you buy. This section does not mean a paid package is currently available in every version.

Purchases and subscriptions are processed by Google Play or Apple App Store, and that store's terms also apply to payment, renewal, cancellation, refunds, and receipts. Unless the purchase screen says otherwise, a subscription may renew automatically at the end of its billing period. Cancel it in your store account settings within the time specified by the store; deleting the App does not cancel a subscription. Refund requests should be made to the relevant store.

Pro access may be verified through RevenueCat. Access depends on store/RevenueCat verification, connectivity, and the status of the relevant store record. If restore-purchase functionality is available, use the store account that made the purchase. A technical outage or store verification delay may temporarily affect access.

6. Intellectual property and license

The App software, design, text, icons, marks, and other Publisher-provided content are protected by applicable intellectual-property laws. While you comply with these Terms, the Publisher grants you a limited, personal, non-transferable license to use the App. Except where applicable law or a relevant license expressly allows it, you may not copy, sell, distribute, modify, or create derivative works from the App or its content.

The App may include open-source components subject to their own license terms. A license list may be available in the App settings.

7. Availability and changes

The Publisher may update, maintain, add, or remove App features. Changes to an operating system, device, store, network, or third-party service may affect availability. The App is not promised to operate without interruption or error or to achieve a particular result. Mandatory consumer rights remain unaffected.

Links to app stores and calendar services are operated by third parties. Those providers control their services and availability.

8. Limitation of liability

To the extent permitted by mandatory law, the Publisher is not liable for indirect loss, lost business, or loss of anticipated savings/results arising from your entry of incorrect or incomplete information, decisions based on App outputs, outages caused by your device/operating system/store/external calendar provider, or your failure to protect your data.

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited, consumer rights, liability for intentional misconduct or gross negligence, or liability for death or personal injury where law provides otherwise. No term is intended to reduce mandatory legal rights.

9. Privacy and data

For details about data handling, see the Privacy Policy. Replace this link with the published Privacy Policy address before publication. The Privacy Policy explains local data export and deletion, calendar feeds, and notifications.

10. Termination, changes, and governing law

You may end your use at any time by removing the App from your device. If you breach these Terms, or for security or operational reasons, the Publisher may restrict access to the extent permitted by applicable law. Any purchase or subscription relationship remains subject to the relevant purchase terms and store rules.

These Terms may be updated; the current version will be published on this page, and material changes may be communicated through an appropriate channel. Use after the effective date of an update is subject to the updated Terms to the extent allowed by law.

These Terms are subject to mandatory consumer and data-protection laws where you live. The competent courts and consumer authorities are determined under applicable mandatory rules. No jurisdiction clause or waiver is intended to deprive you of rights that cannot lawfully be waived.
