π Hi, I'm @HydrofluoricAcid
Studying Applied Mathematics at New York University. I build small, private, ad-free tools β mostly apps, browser add-ons and self-hosted services. Everything here is free software, and most of it is mirrored on GitHub and Codeberg.

| Watermarking Mini Program | A small Pillow script that tiles a text watermark over photos, with configurable size, colour, rotation, spacing and opacity. |
π€ Upstream contributions
I also send patches to projects I use myself. The most notable:
- Chrome Mask β the upstream of Chrome Simulator.
- Find my IP β a lightweight app that fetches and stores your current IP address.
- Bouncer β helps you pick the right firewall zone for a wireless connection.
- Smoking Tracker β I maintain the Traditional and Simplified Chinese translations.
