Three Simple Spaces

Calm up front. Power tools tucked neatly inside Settings.

1 · Chat

Ask, Read Files & Scan Photos

Attach PDFs, Word documents, CSVs, calendar invites, or camera photos. Every AI reply gives you Copy, Share, 👎 Feedback, and ⋯ More (Save, Side chat, Search online, Report).

2 · Memory

About Me & Saved Notes

Keep personal facts you want remembered in About me and favorite answers in Saved. Stored locally as clean Markdown (me.md) encrypted with AES-256-GCM, with 1-tap export anytime.

3 · Settings + Advanced

Optional Apps & Power Controls

Switch models, toggle Search online, or connect optional local apps (Calendar, Contacts, Notes folder). Power options—auto-switching, Morning Summaries, custom .gguf import, and technical counters—live under Advanced.

Open-Weight Models

Matched to your phone’s memory and storage.

On first launch, Localia recommends a fast, compact 1.1 GB model so you can start right away—and lets you switch to smaller or larger vision/reasoning models anytime in Settings → Model.

On-Device Encryption & Network Airlock

  • Zero accounts, zero cloud backups: Chats, Saved notes, and memory are encrypted at rest with Android Keystore AES-256-GCM (Google Tink) with allowBackup="false".
  • Search online is OFF out of the box: Every network call passes through a single auditable AirlockController.

Diagnostics-First Feedback & Cohort-Suppressed Stats

  • Diagnostics only by default: Tapping 👎 defaults to 0 chat words—or optionally scrubs PII on-device with an editable preview, 30-day auto-purge (across D1 and our private bug-triage mirror), and an instant fb_... deletion receipt.
  • Strictly opt-in daily stats (OFF by default): Optional toggle in Settings → Advanced, capped at <= 2,048 bytes/day with zero device IDs, zero session rows, and k >= 5 minimum-ping cohort suppression on stats views.
100% Free & Open-Weight

Every feature unlocked. Zero subscriptions, zero Pro gates.

Because Localia runs AI directly on your phone’s processor rather than metered cloud GPUs, there are no per-message server bills. Every feature is unlocked out of the box for everyone:

  • Unlimited chats, camera photo scanning & PDF reading
  • Multiple specialist models installed side-by-side without deleting existing ones
  • Automatic smart switching between fast everyday replies and deep reasoning
  • Private Morning Summary across your Calendar, Contacts & local Notes
  • Custom .gguf import via Android Storage Access Framework
  • 1-tap Markdown export & delete for your local me.md memory
FAQ

Frequently Asked Questions

Does Localia really work in Airplane Mode with zero internet?

Yes. Once you download a model onto your phone (1.1 GB recommended), 100% of chat replies, photo/PDF reading, Morning Summaries, and memory lookups run on your phone’s processor with zero internet connection.

How do I install Localia?

Open Localia on Google Play and tap Install. Then open Localia and follow the setup steps to download your first on-device model.

What happens when I turn on “Search online”?

Search online is off by default. When enabled, Localia sends only focused search keywords over a cookie-less HTTPS request to public search sources (or reads a link you pasted) and summarizes the answer on your phone. Your memory, photos, and Connected Apps are never sent.

Is Localia really 100% free? Is there a Pro tier or subscription?

Yes—100% of Localia is free with no Pro tier, no locked model slots, no ads, and no subscriptions. Every model slot, Auto-Switch, Morning Summary, and Connected App works out of the box with no account or card.

Which Android phones are supported?

64-bit ARM (arm64-v8a) phones running Android 10 or newer with at least 3–4 GB RAM (Pocket 0.4 GB) or 6 GB+ RAM (Everyday 1.1 GB, Deep 2.5 GB, Smart Vision 3.8 GB).

Can I rely on Localia for medical, legal, or financial decisions?

No. Compact on-device AI models can make mistakes or omit context. Always double-check important facts and consult qualified professionals for medical, legal, mental health, or financial matters.
