Gentian: tattoo stencil maker

Terms of Use

Published by Benjamin Jacobs (SwellStack Co). Effective 2026-11-15.

The license

Gentian is licensed to you under Apple's Licensed Application End User License Agreement (the standard EULA), which you can read at apple.com/legal/internet-services/itunes/dev/stdeula. That agreement governs your use of the app. The terms below add the details of the plans and what the app can and can't do. Where they differ, Apple's EULA wins.

The free stencil

Gentian is a free download. Opening pictures and making lines is always free. Your first stencil prints, saves and shares in full, with no watermark. A stencil is one sheet on one day: printing, saving and sharing the same sheet on the same day count once. The count is kept on your device and carries over if you delete and reinstall the app.

Plans

From the second stencil on, printing, saving and sharing need one of three plans. Each unlocks the same things. US prices:

The app shows the price in your local currency before you buy. There are no ads and no credits on any plan.

Subscriptions

Refunds

Apple handles all payments, so refund requests go to Apple at reportaproblem.apple.com. We can't issue refunds ourselves.

Restoring a purchase

On a new device, or after you reinstall, open Gentian's Settings and tap Restore purchases while signed in with the Apple Account you paid with. Restore is also on the purchase screen.

What the lines are

Gentian traces the edges that are in your picture. It does not draw, add or fix anything. A blurry or soft picture gives broken lines. You decide which lines to keep with Detail, Cutoff and the eraser, and you are responsible for checking a stencil before you use it.

The size on the page is set by your printer. Every sheet has corner marks 1 inch long so you can measure. Gentian makes no promise that a stencil suits any particular printer, transfer paper or skin.

Your pictures

You need the right to use the pictures you open in Gentian. The sample picture is a public-domain print from The Metropolitan Museum of Art. Gentian never changes or deletes a picture in your photo library.

Changes

If these terms change, the new version will be posted on this page with a new effective date.
