Data Not Collected.
PQ Calc doesn’t collect any data. No accounts, no analytics, no ads, no tracking. Nothing about you, or about your calculations, is ever sent to Avical or anyone else.
This policy covers PQ Calc on iPhone, iPad and Mac, and any email you send us about it.
On your device
PQ Calc saves your current calculation and your settings on your device, so it opens right where you left off. That includes which rows you show, their order and your decimal places. PQ Calc doesn’t send them anywhere.
Handoff
When you use Handoff, PQ Calc passes your current calculation (the value, the selected row, the range, the units, the chart’s scale and the tab you’re on) to your other devices signed in to the same Apple Account, so you can continue there. Handoff carries it between your own devices; Avical never receives it.
Crash reports from Apple
If you’ve chosen to share analytics with app developers in your device’s privacy settings, Apple may send Avical crash reports and basic statistics, such as how many devices use PQ Calc. These come from Apple, not from PQ Calc, and we use them only to find and fix problems. You can turn this sharing off at any time in your device’s settings.
Beta testing with TestFlight
If you test a beta of PQ Calc through Apple’s TestFlight, Apple shares some information with Avical: your device model and an identifier for it, which builds you’ve installed, how often you open them, crash reports, and any feedback and screenshots you send. If we invited you by email, we also see that email address and the name we entered for you; if you joined through a public link, we don’t. We use this only to improve PQ Calc. Apple explains it in TestFlight & Privacy.
If you email us
We use your message and your email address only to reply to you. Support email is kept in our email service, Microsoft 365, and we’ll never add you to a mailing list.
What we’ll never do
We don’t sell your personal information, share it for advertising, or give it to data brokers. If Avical is ever merged with or acquired by another company, information we hold, such as support emails, may pass to the new owner, and we’ll require them to honor this policy.
Your choices
PQ Calc holds nothing about you, so there’s nothing in the app to see, correct or delete. If you’ve emailed us and want a copy of what we have, or want it deleted, write to [email protected].
Children
PQ Calc doesn’t collect information from anyone, including children.
Changes
If this policy changes, we’ll update this page and the date at the top. If PQ Calc ever starts collecting data, we’ll say so here before that version is released, and its App Store privacy label will change with it.
