Terms of use

Using Dayvia

Dayvia offers personalized travel planning suggestions from the flights and usual routine you enter. You must be at least 18 to use it. Keep your account secure, provide accurate information and use the service lawfully. Check flight dates, schedules and time zones against your booking. Dayvia is not an airline, travel agent or emergency service, and does not monitor your flights for changes.

General guidance, not medical care

Dayvia provides general wellness and travel guidance. It is not a medical device and does not diagnose, prevent or treat a condition. Its timing estimates have not been clinically validated, and no reduction in jet lag or other result is guaranteed. Do not reduce needed sleep, ignore fatigue or follow an unsafe suggestion. Seek professional advice about medicines, pregnancy, health conditions or persistent sleep problems. Do not drive or carry out safety-critical tasks when tired.

Free trips, purchases and subscriptions

The first eligible journey is free. A one-time trip purchase unlocks one additional journey; it does not renew. An annual subscription lets you unlock eligible trips while it is active. A journey can include connections and a return trip. Deleting a journey does not replenish a used free allowance or trip credit. A free first journey is not a subscription trial.

Purchase availability, the local price, currency, billing period and any applicable tax are displayed by the store before confirmation. Payment is charged to your Apple or Google account. Annual subscriptions renew automatically for another year unless you cancel renewal through that store under the terms shown at purchase. Any price change is handled under the store’s notice and consent requirements. Deleting the app or your Dayvia account does not cancel billing.

Manage or cancel renewal through your Apple or Google account. Normal cancellation takes effect at the end of the paid period, as shown by the store. Previously unlocked plans remain available after ordinary subscription expiry while the Dayvia account exists; a refund, reversal or account deletion may affect access. Use Restore purchases with the original Dayvia and store accounts for eligible purchases. One-time trip credits and unlocks are recorded against your Dayvia account, so contact support if they are missing.

Request a refund through the store that charged you, or contact us for help locating the transaction. Eligibility depends on applicable law and the store’s process. These terms do not waive your statutory cancellation, refund or other consumer rights. Any trial or promotional offer applies only if expressly shown before you confirm it.

App license and intellectual property

Apple’s Standard Licensed Application End User License Agreement applies to the iOS app. These service terms supplement that license and do not replace its mandatory provisions. On other platforms you receive a personal, limited, non-exclusive license to use Dayvia, subject to applicable law and store rules. A purchase grants access to features; it does not transfer ownership of the software.

You keep your rights in the information you enter and permit us to process it to provide the service as described in the privacy policy. Dayvia’s software, name and design remain the property of their respective owners. Do not access another person’s account, bypass purchase controls, distribute malicious software or misuse the service. Open-source and place-data licenses continue to apply; nothing here restricts rights those licenses or applicable law give you.

Availability and changes

Saved, unlocked plans can be opened offline. Sign-in, synchronization and verification of new purchases need an internet connection. Reminder delivery depends on your device settings and operating system, so do not rely on a reminder for a safety-critical task. We maintain and may change the service, but cannot promise uninterrupted availability. For a material reduction or discontinuation of paid features, we will give notice and provide any remedy required by applicable consumer law.

Account closure

Request account deletion in Settings or through our account-deletion page. If the in-app request fails, email [email protected]. A confirmed scheduling request displays its deletion date. Deletion removes access to the account and its plans, so retain information you need beforehand. Store billing must be canceled separately. We may restrict an account where reasonably necessary to address unlawful conduct, fraud or harm, and provide an explanation and a way to contact us unless doing so would compromise security or a legal obligation.

Responsibility and consumer rights

You remain responsible for travel and health decisions, but this does not limit our obligations under applicable law. We do not exclude liability for fraud, intentional misconduct, death or personal injury where caused by our negligence, or any liability that cannot legally be excluded. Mandatory rights concerning digital services and defective performance remain available. Estonian law applies to these terms, without depriving consumers of mandatory protections or the right to bring a claim in a court available under the law of their country of residence. Contact us if something goes wrong so we can try to resolve it.

Changes and contact

We may update these terms for changes to the service or law. We will identify the revision date and give notice of material changes as required. Changes do not retrospectively remove rights attached to a completed purchase. If a change requires your agreement, we will request it. Contact Qorinx OÜ at [email protected] or at the postal address below with questions, complaints or support requests.
