TC Calculator — Privacy Policy
Effective date: 2026-06-18
TC Calculator ("the app," "we," "us") is an iPhone app that adds, subtracts, and converts SMPTE timecode for video and film work. We designed TC Calculator to work entirely on your device. This policy explains, in plain language, what the app does and does not do with your information.
The short version
We do not collect, transmit, sell, or share your personal information. TC Calculator has no servers, no account system, and no analytics or advertising. Everything you enter stays on your iPhone.
Information we collect
None. TC Calculator does not require an account and does not ask for your name, email, phone number, or location. We do not operate any server that receives your data, and the app contains no analytics, tracking, or advertising software.
Information stored on your device
To do its job, the app stores the following locally on your device:
-
Your calculation history (the timecodes and results you confirm).
-
Your settings (such as frame rate and drop-frame selection).
This information is saved in your device's local app storage so the app can show your history and preferences. It is not transmitted to us or to anyone else.
How we share information
We do not share your information, because we do not collect it. TC Calculator contains no third-party SDKs that receive your data.
Children's privacy
TC Calculator is a general-purpose utility and is not directed to children. We do not knowingly collect any information from anyone, including children.
Data retention and deletion
Because your data is stored only on your device, you remain in control of it. Clearing the in-app history or deleting TC Calculator from your iPhone removes the app's locally stored data.
International users
TC Calculator processes everything locally on your device and does not transfer your data across borders, because no data leaves your device.
Changes to this policy
If we change this policy, we will update the "Effective date" above and publish the new version at the same location. Material changes will also be reflected in the app's Legal section.

If you have questions about this policy, contact us at: info@denzolab.com.

The app
TC Calculator adds, subtracts, and converts SMPTE timecode across multiple frame rates, including drop-frame and non-drop, and displays conversions to frames, seconds, and feet+frames. The app is provided free of charge.
Not a safety-critical tool
TC Calculator is an informational convenience tool only. It is not a broadcast master clock, sync device, or safety-critical timing system, and it must not be relied upon for any safety-critical, operational, or broadcast-critical decision. Times and frame counts shown are based on the values you enter and your device's clock. Always follow your production's official references, timecode sources, and procedures.

The app is provided "as is" and "as available," without warranties of any kind, whether express or implied, including fitness for a particular purpose. We do not warrant that the app will be uninterrupted, accurate, or error-free.
Limitation of liability
To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, or consequential damages, or for any lost work or other loss arising from your use of or reliance on the app.
Changes to these terms
We may update these Terms from time to time. We will update the "Effective date" above and reflect material changes in the app's Legal section. Continued use after changes means you accept the updated Terms.
Governing law
These Terms are governed by the laws of Japan, without regard to conflict-of-law rules.
Apple
Apple is not a party to these Terms and is not responsible for the app. The Apple Standard End User License Agreement also applies to your use of the app and is available at:
