Terms of use

The licence

Dayproven is licensed to you under Apple's Licensed Application End User License Agreement (the standard EULA). The points below add to it; where they differ, the standard EULA applies.

What Dayproven is, and is not

• Dayproven counts days from the location record on your iPhone and the stays you enter, and shows the thresholds that each test's published source sets.
• It does not say whether you are resident anywhere, whether you owe tax, or whether you may stay in a country, and it is not tax, legal or immigration advice. Several tests depend on facts a phone cannot know (where your home is, your ties to a country, your visa or residence permit); the app shows those as the rule's other conditions.
• A count is only as complete as the record behind it. Location readings depend on iOS, your settings and your phone being on; days the record cannot settle are shown as unresolved, not guessed. Check the record and take professional advice before relying on a count.

Dayproven Pro

Dayproven Pro is a one-time purchase made through the App Store. It unlocks PDF and CSV exports and adding stays from before you started using Dayproven. Every count stays free. The price is shown in the App Store before you buy.

Refunds and cancellation

Purchases are made from Apple, and refunds are requested from Apple: see Request a refund for apps or content that you bought from Apple. If Dayproven gets a count wrong, tell us at residency@greyledger.co.uk so we can fix it.
