You may not reverse engineer, decompile, modify, or redistribute the software or any portion thereof.

Sales and subscription terms

Eşik offers logging, the doctor visit report (PDF) and data export free of charge. Trigger analysis, 21-Day Experiments, unlimited graph history, the full Monthly Threshold Report, Lock Screen and medium Home Screen widgets, Siri shortcuts and medication tracking are among the features available through an auto-renewable subscription (Eşik Plus, monthly or yearly).

• Automatic renewal: Subscriptions automatically renew for the same tier and billing duration unless auto-renewal is turned off at least 24 hours prior to the conclusion of the current subscription cycle.
• Managing and canceling subscriptions: Automatic renewal can be canceled at least 24 hours before the end of the current period through your Apple ID / App Store account settings. You can manage or cancel your subscription at any time by going to iOS Settings → Apple Account → Subscriptions or by tapping “Manage Subscription” in Eşik Settings.
• Access upon cancellation: If you cancel your subscription, you retain full access to Eşik Plus features through the end of the current paid billing cycle. No partial refunds are issued for unused time.
• Refund requests: Since billing is handled solely by Apple, refund requests must be submitted directly to Apple Support in accordance with App Store guidelines.
