Signetry: Logo & Watermark

Signetry makes a simple mark - a monogram, a wordmark, a small emblem - and puts it on your photos.

Everything happens on your device. There is no account, no upload and no subscription. Signetry has no internet permission at all, so nothing you make can leave your phone unless you share it yourself.

MAKE A MARK
- Start from one of twelve original layouts, or from a blank canvas
- Combine text and shapes on as many layers as you need
- Around 45 built-in shapes and icons: circles, rings, hexagons, shields, badges, stars, leaves, droplets, frames, rules and more
- Eleven typeface styles, with bold, italic, small caps and letter spacing
- A full colour palette plus hue, saturation and brightness sliders
- Square, wide 16:9, banner 3:1 and portrait 3:4 canvases
- Alignment guides that snap to the canvas and to your other layers
- Undo and redo up to 60 steps, with automatic saving

EXPORT A TRANSPARENT PNG
- Export at 64, 128, 256, 512, 1024 or 2048 pixels
- A real alpha channel, so your mark sits cleanly on any background
- A checkerboard preview shows exactly which parts of the file will be transparent
- Save to your Photos library or to a folder you choose, or share the file directly

WATERMARK YOUR PHOTOS
- Pick photos with the Android photo picker, so Signetry never asks for access to your whole gallery
- Nine positions, plus size, margin and opacity controls
- Size and margin are measured against each photo's shorter edge, so portrait and landscape shots get a mark of the same visual weight
- A live preview on your first photo before anything is written
- Batch up to 60 photos at a time, as JPEG or PNG
- Your originals are never modified or deleted: every result is a new file ending in "-marked"
- If a photo cannot be read, it is listed with the reason and the rest of the batch still runs

BUILT TO BE HONEST ABOUT ITSELF
- The shape library is drawn by Signetry in code, so nothing is copied from a third-party icon set
- Text uses the typefaces already on your device, so no fonts are bundled or redistributed
- Marks you create are yours; Signetry places no restriction on how you use them
- Back up your marks to a single file, and preview a backup before restoring it

WHAT SIGNETRY DOES NOT DO
Signetry does not generate logos with AI, does not search trade mark registers, and cannot tell you whether a name or mark is already in use or registrable. It is a drawing tool, not legal advice. If a mark matters to your business, take proper advice before relying on it.
