Help & FAQ

A full paint engine, free from your first stroke. Seven mediums, each with its own feel: Basic, Oil, Watercolor, Charcoal, Chalk, Ink and Pastel. Nine papers, from smooth to canvas, kraft and blueprint. Premium adds the tools and papers of the old masters.

A way to check your painting while you can still fix it:

• Values: grayscale, so you read the light and dark
• Temperature: warm against cool
• Saturation: where your color works and where it has gone muddy
• Contrast: the lights and darks pushed apart, so the structure reads clearly

They come with Premium.

Yes, with Premium. Tap Guides and turn on the Golden spiral, Golden section or Golden triangles, or dynamic symmetry, harmonic armature and rabatment. The guides are just for you and never show in your export. The rule of thirds, diagonals, center and grid are free.

Trazu is free to use, with no time limit. Premium is one payment, not a subscription. You see the price in your currency before you pay, and Apple or Google handles the payment.

No. Your Premium is still yours. It belongs to your App Store or Google Play account.

1. Open the Premium tab.
2. Tap Restore purchase.

Use the same account you bought with. There’s no separate login. Apple and Google are separate stores, so a purchase on iPhone does not carry over to Android.

In Drawings, tap the three dots on a drawing, choose Export, then PNG or JPEG. Then:

• iPhone and iPad: the share sheet opens. Choose Save Image to keep it in Photos.
• Android: choose Save and pick where it goes, or Share to send it.
• Mac: choose a folder to save it in.

A PNG with a Transparent background comes with Premium.

In Drawings, tap the three dots on the drawing and choose Delete. We ask you to confirm first, because a deleted drawing cannot be recovered.

Yes. Your drawings are saved on your device and never uploaded, and there’s no account.

Trazu sends anonymous usage statistics and crash reports, tied to a random ID. They carry no artwork and nothing that identifies you. Their only job is to help us make Trazu better.

On iPhone, iPad, and Android, uninstalling Trazu removes your drawings, so export anything you want to keep. On Mac, deleting the app does not remove its data: delete the drawings in the app first if you want them gone.
