Rumima docs

Getting started

Rumima is an AI visual knowledge platform — a fast, voice-driven canvas for building mind maps, troubleshooting trees, and living documentation. It runs fully on your device; the network is only used for licensing and optional sync.

Rumima ships in three editions:

• Free (Play) — the ad-supported edition for everyday personal maps. Distributed on Google Play for Android.
• Pro — €24.99/yr — everything unlocked, ad-free. Available on Windows via this website and on Android via Google Play.
• Enterprise — seat-based licensing with a central admin portal. Web only, purchased and managed on this website.

Install on Windows

The Windows build is delivered through the website so it can be tied to your Pro or Enterprise entitlement.

1. Sign in on the Download page with the account that holds your Pro subscription or Enterprise seat.
2. Download the signed installer, Rumima-Setup-x64.exe.
3. Run the installer and follow the prompts. It installs per-user and requires no administrator rights.
4. Launch Rumima. On first start it prompts you to sign in and activate — see Activating your license.

System requirements: Windows 10 or 11 (64-bit), 4 GB RAM, and roughly 300 MB of disk space.

Install on Android

On Android both editions are published on Google Play, so updates and billing are handled by the Play Store.

• Rumima (Free) — the ad-supported edition: play.google.com/…/rumima
• Rumima Pro — the ad-free, fully unlocked edition: play.google.com/…/rumima.pro

Requires Android 8.0 or newer. After installing Pro, open the app and sign in to activate your license.

Activating your license

Activation binds your subscription to the device you are using. It happens automatically the first time you sign in:

1. Sign in with your Agrarobotics account (Enterprise users sign in with the identity your admin assigned).
2. Rumima computes a device fingerprint — a stable, non-reversible hash of hardware and OS attributes — and registers it as an activation.
3. The app calls the licensing server (a Rust service on Google Cloud Run), which verifies your entitlement and returns an Ed25519-signed license token.
4. The token is stored locally. From then on Rumima validates it against the embedded public key at launch — no network round-trip required.

A token is a small signed payload. Its claims look like this:

{
  "lid":      "lic_7Q2f9K4mXb",        // license / activation id
  "org":      "org_agrarobotics",      // null for personal Pro
  "tier":     "pro",                    // free | pro | enterprise
  "seats":    1,                        // seats this token represents
  "features": ["export.all", "encryption", "sync", "anki"],
  "exp":      1752566400             // unix expiry — now + 10 days
}

The signature covers the entire payload, so the claims — including tier, features, and exp — cannot be edited without invalidating the token.

Offline grace & revalidation

Rumima is built to keep working where the network doesn't — on a plane, in a plant, or on a field laptop. Every successful online check-in returns a fresh token with exp = now + 10 days.

• While the current token is valid, the app runs fully offline — validation is a local signature check against the embedded public key.
• When the remaining runway drops below about 3 days, Rumima silently refreshes in the background the next time it reaches the server, resetting the clock to a full 10 days.
• Because exp lives inside the signed payload, it can't be forged or extended by editing local files or rolling back the system clock past the signature.

Only if a device stays offline for the entire grace window does the token lapse; the next successful sign-in re-issues one immediately.

Managing your devices

A Pro subscription covers a small number of devices at once — for example your Windows PC and your Android phone. Each activation is one registered device fingerprint.

To free up a slot when you replace or retire a machine:

1. Open your Account portal and go to Devices.
2. Find the device you no longer use and choose Deactivate.
3. That activation is released at once; the device loses its license at its next check-in, and the freed slot is available for a new install immediately.

Enterprise admin guide

Enterprise licensing is seat-based and managed centrally. Admins never touch individual token files — everything is done from the portal.

1. Buy seats on the website. Choose a seat count (volume discounts apply) and complete checkout to create your organization's seat pool.
2. Sign in to the Enterprise Portal with your admin account.
3. Assign seats to users by email. On their next sign-in, Rumima activates against the assigned seat automatically.
4. Revoke or reassign a seat instantly when someone leaves or changes roles — the old device loses access at its next check-in.
5. Add seat packs mid-term as the team grows; packs are prorated to your renewal date.
6. Renew annually from the portal to keep the whole pool active.
7. Review audit logs — activations, device registrations, seat changes, and admin actions are all recorded and exportable.

Licensing architecture

Rumima's licensing runs on a small, purpose-built stack on Google Cloud. Signing keys stay server-side; every client only carries the public key needed to verify tokens.
