Terms of Use
Last updated: October 2026
These terms apply to your use of the Manual Exposure app, made by George Koultouridis. The app is also licensed to you under Apple's Standard Licensed Application End User License Agreement (EULA). By using the app, you agree to both.
Full version
Some calculators require the full version. It is a one-time purchase through Apple, not a subscription. Payments and refunds are handled by Apple under its terms. If you reinstall the app or use another device with the same Apple ID, use "Restore Purchases" to get the full version back for free.
Calculations and equipment data
The calculators give estimates based on common photography formulas and on the equipment data in our catalog. Results depend on your equipment, settings and conditions, so always check your photos. We do our best to keep the catalog accurate, but we can't guarantee that every value is correct.
Your use of the app
Use the app only for lawful purposes. Don't try to copy, extract or reverse engineer the equipment catalog or the app.
Availability
We may change, update or stop features of the app. The equipment catalog requires an internet connection; the rest of the app works offline.
Liability
The app is provided "as is". To the extent permitted by law, we are not liable for indirect or consequential losses, such as missed shots, and our total liability is limited to the amount you paid for the app. Nothing in these terms limits rights you have as a consumer under the law of your country.
Governing law
These terms are governed by the laws of the Netherlands. If you live in the European Union, you also keep the protection of the mandatory laws of your country.
Changes
If these terms change, the new version will be included in an app update with a new date above.
