LocaLens — Privacy Policy

Last updated: September 30, 2026

LocaLens ("the app") is an offline translator for photos, typed text and live conversation. Everything you photograph, say or type is processed on your device and never leaves it — translation, text recognition in photos and speech recognition all run on the phone, and work in flight mode. LocaLens has no account and does not collect your content.

The app uses the internet for two things only: downloading its translation and speech models once, and — only if you agree — sending anonymous usage statistics. Both are described below. LocaLens shows no ads and contains no advertising or tracking SDK.

What stays on your device

• Photos and camera images you translate — read on the device; LocaLens does not upload them.
• Microphone audio in Conversation and voice input — turned into text on the device while you use the feature; audio is not recorded to storage or sent anywhere.
• Text you type, paste or share into the app, and all translations — produced and kept on the device.
• Your settings (languages, voice speed, earbuds mode and similar) — stored in the app's private storage.

Uninstalling the app deletes all of it, including the downloaded models.

Model downloads

Translation, speech and text-recognition models are downloaded when you choose them (for example in the setup wizard or the Settings tab). They come from public model hosts (Hugging Face and GitHub) and from LocaLens' own download server (hosted on Cloudflare). Like any web server, these services receive technical connection data such as your IP address and device type while a download runs; LocaLens sends them nothing about you or your content, and our own server does not store IP addresses.

Optional anonymous usage statistics

Off unless you agree. The app may ask once whether you want to share anonymous usage statistics to help improve LocaLens; you can change your answer at any time in the app's settings. If you agree, the app sends one small summary per day to LocaLens' own server (Cloudflare), containing:

• Languages: your phone's language and the app's display language; which language pairs you translate between, per feature, with counts; languages you add or remove.
• Feature use: how often you use the camera, typed text, conversation, earbuds mode and voice playback; conversation time in broad ranges; whether you finished the setup and tours.
• Quality and speed: signs that a result needed correcting (for example switching the detected language); how long models take to load and translate; errors and crashes (the error type and the part of the app involved, never text).
• Downloads: which models were downloaded or failed, and free storage in broad ranges.
• Device: app version, Android version, device model, memory size range.
• A random statistics ID created on your device (not your advertising ID or any other device ID), so days of use can be counted. You can reset it in settings.

The statistics never include your photos, audio, recognized speech, typed text or translations, and are not linked to your name, email or advertising ID. Our server does not store IP addresses. Daily summaries are kept for up to 24 months, then deleted.

Permissions and why they're used

• Camera — to photograph text you want translated. Images are processed on the device.
• Microphone — for Conversation and voice input. Speech is recognized on the device while the feature is on.
• Internet — to download models and (if you agree) send anonymous statistics.
• Notifications, foreground service (data sync), wake lock — to show download progress and keep large model downloads and live conversations running reliably.

Data sharing

LocaLens does not sell or share your content with anyone — it never has it. The only third parties involved are the model hosts named above (to deliver downloads) and Cloudflare (which runs LocaLens' download and statistics server).

Children

LocaLens is a general-purpose translation tool and is not directed at children under 13.
