Trazu
Trazu is a drawing app with a free tier and an optional Premium upgrade. The free tier includes all drawing tools and lets you save up to 10 drawings. Premium removes that limit for a one-time purchase, giving you unlimited drawings, plus the four study views (Value, Temperature, Saturation, Contrast).
You own everything you draw. Your drawings stay on your device. We never upload, access, or store your content.
Premium is a one-time purchase processed through the App Store (iOS) or Google Play (Android). The price is shown in the app in your local currency. Refund policies are governed by the respective store.
The app works fully offline. No internet connection is required for any feature. We work to keep Trazu running and may change or improve features over time. If we ever discontinue it, we'll give reasonable notice and won't charge you for a paid period you can no longer use.
Trazu comes as is. Like any software it isn't perfect, and we can't promise it will always work without errors or interruption. To the extent the law allows, we're not liable for damages arising from your use of the app. None of this removes the rights you have under the consumer laws of your country.
We may update these terms. If we make an important change, we'll note it here and update the date below. Continued use of the app after a change means you accept the updated terms.
