TERMS (EULA)

Last Updated: October 14, 2026

Introduction

These General Terms and Conditions ("Terms") serve as the End User Licence Agreement (EULA) for the Dayline AI app and govern your use of the health and fitness application ("App") provided by AllBlazing BV ("we," "our," or "us"). By accessing or using the App, you agree to be bound by these Terms. If you do not agree, please do not use the App. We comply with applicable law, including the EU General Data Protection Regulation (GDPR), the EU AI Act where applicable, and Dutch law.

Use of the App

  • Personal Use: Dayline AI is provided for personal, non-commercial use only. You may not use the app for any commercial purpose without our express written consent.
  • Age Requirement: The App is intended for users aged 18 and over. Users under 18 should not use the App without parental supervision and consent.
  • Prohibited Uses: You may not: (a) reverse engineer, decompile, or disassemble the App; (b) use the App to violate any laws or regulations; (c) interfere with the App's operation or security; (d) use automated systems to access the App without permission.
  • Account Responsibility: You are responsible for maintaining the security of your device and Apple ID. We are not liable for unauthorized access to your device or Apple account.

Health Data and Privacy

The App accesses health data from Apple Health with your permission. Raw samples stay on your device. Daily summaries may be stored as described in our Privacy Policy. With your permission the App may use Apple Weather (city-level location only). You grant Apple Calendar through iOS permissions and choose calendars under Settings → Apple Calendar → Choose calendars. Google Calendar is an optional Pro connection with read-only access to calendars you select. It is subject to the Google API Services User Data Policy, including the Limited Use requirements, as set out in the Privacy Policy. Both calendars may use event titles, start and end times, busy/free status, and your RSVP. Birthday and holiday feeds, and cancelled or declined events, are excluded. Locations, descriptions, attendees, and attachments are not read. If you enable it, Outlook (Pro, optional) is used to read subject and body text from at most 12 recent messages to derive lifestyle themes. Outlook is off by default. All such data is processed as described in the Privacy Policy. Health summaries, calendar-derived values, and, when Outlook is enabled, message text from at most 12 recent messages may be sent to our AI provider as described there. We do not keep raw Outlook message text or a mailbox copy, we do not access email attachments, and we do not sell your data. Revoking an Apple permission in iOS Settings stops future access. It does not, by itself, remove values already stored. Turning a connection off in the App, and Delete All Data, are described in the Privacy Policy.

App Features and Data Use

Dayline AI provides daily health insights ("Daylines"), pattern analysis, and AI-generated explanations based on your biometric data (e.g. HRV, resting heart rate, sleep, activity). Pro subscribers receive extended pattern context (up to 120 days of history), fuller AI insights, and optional integrations (Weather, Apple Calendar, Google Calendar, Outlook) as described in the App and Privacy Policy. A Dayline may refer to a calendar event in general terms. How long device history and server repetition-prevention memory are kept is set out in the Privacy Policy. Optional email integration lets you connect Outlook (Pro, optional) so the App can use subject and body text from at most 12 recent messages to contextualize your Dayline; you must enable this feature yourself. We process data only to provide these features. We are not responsible for the accuracy of data provided by Apple Health, Apple Weather, Apple Calendar, Google Calendar, or Outlook.

Medical Disclaimer and AI-Generated Content

Medical Disclaimer:
Dayline AI provides insights for informational purposes only. The App is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or medical condition. The App is not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Never disregard professional medical advice or delay in seeking it because of information provided by the App.

AI-Generated Content and EU AI Act Transparency:

  • AI System: Insights are generated using artificial intelligence. The AI uses your health summaries and, when you enable them, calendar-derived context and Outlook message text, as described in the Privacy Policy, to create personalized, plain-language explanations. A short description drawn from a calendar title may be sent for a single request. It is not stored as a calendar record. This is a limited-risk AI system under the EU AI Act; we provide transparency and do not use the App for prohibited purposes.
  • No Guarantees: We do not guarantee the accuracy, completeness, or usefulness of AI-generated insights. Insights may contain errors, inaccuracies, or inappropriate content.
  • Limitations: The AI system has limitations and may not always provide relevant or accurate insights. Insights are based on patterns and correlations, not medical expertise.
  • Your Responsibility: You are responsible for evaluating the appropriateness of insights for your situation. Do not rely solely on AI-generated insights for health decisions. Human oversight (e.g. consulting a healthcare provider) is recommended where relevant.

Subscriptions and Right of Withdrawal (Dutch Consumer Law)

Pro subscriptions are managed through Apple's App Store. By purchasing a subscription, you enter into a contract with AllBlazing BV.

  • Subscription Terms: Monthly and yearly Pro subscription options are available. The current price for each option is displayed in the App (paywall) and in the App Store at the time of purchase and may vary by region. You agree to the price and billing interval shown before you confirm purchase.
  • Auto-Renewal: Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period. You can manage and cancel in Settings → [Your Name] → Subscriptions.
  • Cancellation: You can cancel your subscription at any time through your Apple ID Account Settings. Cancellation takes effect at the end of the current billing period.
  • Right of Withdrawal: Under Dutch consumer law (Distance Selling Act), you have 14 days to withdraw from a subscription contract without giving a reason, starting from the day you receive access. If you have started using the Pro features, you may be charged for the period of use. See our Withdrawal form (EU) if you wish to exercise this right in writing.
  • Refunds: Refund requests are handled by Apple according to their refund policy. For refunds outside Apple's policy, contact support@daylineai.com within 14 days of purchase.
  • Price Changes: We reserve the right to change subscription prices. Existing subscribers will be notified 30 days in advance. Price changes apply to renewals only, not current subscription periods.

Limitation of Liability (Dutch Law)

To the maximum extent permitted by Dutch law (including the Dutch Civil Code), AllBlazing BV's liability is limited as follows:

  • Exclusion: We exclude liability for indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of data, loss of profits, or health-related consequences.
  • Maximum Liability: Our total liability for direct damages shall not exceed the amount you paid for the App (including subscriptions) in the twelve months preceding the claim, or €100, whichever is higher.
  • Third-Party Services: The App integrates with third-party services including Apple (Health, Weather, Calendar), Google (Calendar, optional and read-only), Microsoft (Outlook), and our AI provider. Google Calendar use is subject to Google's API Services User Data Policy, including the Limited Use requirements. Your use of optional Google Calendar and Outlook is subject to those providers' terms and privacy policies. We access only the data described in our Privacy Policy.
  • Force Majeure: We are not liable for failures due to circumstances beyond our reasonable control, including but not limited to third-party service failures (e.g. our AI provider, Apple, Google, Microsoft), network issues, or device malfunctions.
  • AI Content: We are not liable for errors, inaccuracies, or inappropriate content in AI-generated insights, as stated in the Medical Disclaimer section.
  • Consumer Rights: Nothing in these Terms limits your rights as a consumer under mandatory Dutch consumer protection law.

Governing Law and Dispute Resolution

These Terms are governed by Dutch law (Nederlands recht), including the Dutch Civil Code (Burgerlijk Wetboek) and consumer protection regulations.

  • Jurisdiction: Any disputes arising from these Terms or your use of the App shall be subject to the exclusive jurisdiction of the competent courts in The Netherlands, specifically the courts of The Hague (Rechtbank Den Haag) for business disputes, or your local court if you are a consumer.
  • Consumer Disputes: If you are a consumer, you may look up an approved out-of-court dispute resolution body through the European Commission's consumer redress portal (consumer-redress.ec.europa.eu/dispute-resolution-bodies). The European Online Dispute Resolution platform closed on 20 July 2025.
  • Applicable Law: Dutch law applies, including but not limited to: Dutch Civil Code, Consumer Rights Directive, Distance Selling Act, GDPR Implementation Act (UAVG).
  • EU Consumer Protection: If you are an EU consumer, you also benefit from mandatory consumer protection laws of your country of residence that cannot be excluded by these Terms.

Changes to Terms

We reserve the right to modify these Terms at any time. Material changes will be notified through the App or via email. Your continued use of the App after such changes constitutes acceptance of the modified Terms.
