Privacy

What we don't do

No cookies. No third-party trackers, ads, or analytics scripts — no Google Analytics, no Meta Pixel, nothing like that. No persistent identifier is ever written to your device for tracking purposes.

Mini analytics

Visiting the live site (fontane.studio) briefly logs three kinds of event, none of which can identify you personally:

• Page visits— counted via a one-way hash of your IP address, your browser's user-agent, and the calendar date, combined with a private salt. That hash changes every day and can't be reversed back into your IP — it only lets us approximate how many different people visit per day, without storing your actual IP anywhere. We also record the referring site's hostname only (e.g. "google.com"), never a full URL or query parameters.
• Time on site — how many seconds a visit lasted, with no identifier attached at all.
• Font exports— which file format you exported (e.g. "otf"), with no identifier attached.

None of this fires from local development or preview deployments — only the real production site. You can opt out for a given visit by adding ?notrack to the URL (e.g. fontane.studio/?notrack) — every beacon is skipped client-side, nothing is even sent. This is processed under legitimate interest (GDPR Art. 6(1)(f)) — understanding rough usage without identifying anyone.

Your drawings and fonts

Everything you draw and tag — strokes, glyphs, metrics, settings — is saved only in your own browser's local storage. We never see it, and it's never sent to our servers unless you explicitly choose to:

• Export a font, JSON, skeleton SVG, or FFF project file — generated entirely in your browser and offered to you as a download; nothing is uploaded.
• Publisha font to the Marketplace — this uploads the compiled font file plus the name you chose to our storage, along with a small metadata record (font name, glyph count, publish date, download count). Once published, it's public — anyone with the link, or browsing the Marketplace, can view and download it. There's no account system, so a published font currently can't be edited, renamed, or taken down by request through the app — double-check what you're publishing beforehand.

Infrastructure

The site is hosted on Vercel (application and edge network), with Supabase as our database and file storage provider for published fonts and the anonymous analytics described above. We don't run any servers of our own.
