FastMask – Fastmail Masks Live

FastMask is a fast, private, native Android client for managing your Fastmail masked email addresses. Masked emails are disposable forwarding addresses that protect your real inbox. Use a different one for every website, track who leaked your data, and switch off any address that gets abused — without giving up your real email anywhere. FastMask brings the masked-email features that already exist on Fastmail's web app to your phone, in a calm, distraction-free interface designed for one thing: getting in, copying or creating an address, and getting back to whatever you were doing. FEATURES • View all your masks in a clean list, sorted by latest activity (not creation date) • Create new masks with custom descriptions and domain associations • Enable, disable, or archive masks without losing the address • Edit description, domain, and forwarding URL • One-tap copy to clipboard with subtle haptic feedback • Search and filter by Active / Off / Archived • Quick stats: how many messages each mask has received, when the last one arrived • Settings screen with language picker, contact link, and logout DESIGN • Warm-ink palette — parchment cream and ink navy, not the usual blue • Instrument Serif headings, Inter Tight body, JetBrains Mono for addresses • Light and dark mode, both following your system setting • Smooth shared-element transitions between list and detail • Subtle, restrained motion — never in the way PRIVACY & SECURITY • Zero tracking. Zero analytics. Zero third-party SDKs. • Your Fastmail API token is encrypted on-device using EncryptedSharedPreferences • The app talks directly to api.fastmail.com over HTTPS — no servers in the middle • Network Security Config pins trust to the system CA store • Release builds log nothing about your network traffic • Screens are FLAG_SECURE — the token never leaks to screenshots or screen recording • Open source under MIT license — verify everything for yourself LANGUAGES Full UI translations: English, Polish, Spanish, German, French, Italian, Portuguese, Dutch, Russian, Ukrainian, Turkish, Arabic, Hindi, Bengali, Chinese (Simplified), Japanese, Korean, Vietnamese, Thai, Indonesian.
