Terms of Use

Last updated: 23 September 2026

These terms cover your use of the Apertia mobile app, provided by Volkan Günay (Vomcore), Ankara, Türkiye. Installing or using the app means you accept them. Contact: hello@vomcore.com.

What you get

A personal, non-exclusive, non-transferable licence to use Apertia on devices you own or control. The app, its design and artwork stay ours; your kits and settings are yours.

Calculations are estimates

Depth of field, hyperfocal distance and blur are calculated with the standard thin-lens model and an acceptable circle of confusion. Real results depend on your lens design, focus accuracy, print or viewing size and your own standard of sharpness; the bokeh preview is an illustration of blur size, not a render of your lens. Use the numbers as a guide and check critical shots on the camera.

Free and paid

Free use includes the depth of field and hyperfocal calculator, the side-view diagram and one saved kit. Apertia Pro unlocks the bokeh preview, the hyperfocal table, unlimited kits and A/B compare.

• Subscriptions (weekly, monthly, yearly) renew automatically unless cancelled at least 24 hours before the end of the current period. Cancel any time in your App Store account settings; cancellation takes effect at the end of the paid period.
• The yearly plan starts with a 3-day free trial. If you do not cancel before the trial ends, it becomes a paid yearly subscription. The trial is offered once per subscription group, per App Store account.
• Lifetime is a one-time purchase, not a subscription, and carries no free trial.

Prices are shown in the app in your local currency before you buy. Payment is taken by Apple, and refunds are handled by Apple under its own rules — write to us and we will help you ask.

Apple’s standard Licensed Application End User License Agreement also applies: apple.com/legal/internet-services/itunes/dev/stdeula.

Restoring a purchase

Because there is no account, your purchase is tied to your App Store account. On a new device, sign in with the same account and tap “Restore” on the Pro screen or in Settings. Kits and settings are stored on the device and do not move to a new one by themselves.

Acceptable use

Do not decompile, resell or redistribute the app, or try to unlock paid features by tampering.

No warranty, and limits

Apertia is provided “as is”, without warranty of any kind. To the extent the law allows, our total liability for any claim related to the app is limited to what you paid for it in the twelve months before the claim. Nothing here limits liability that cannot be limited by law, and your statutory consumer rights are unaffected.

Changes and ending

We may update the app and these terms; material changes are published here with a new date. You can stop using Apertia at any time by deleting it. If you breach these terms, the licence ends.

Law

These terms are governed by the laws of the Republic of Türkiye, without prejudice to mandatory consumer protections in your country of residence.
