Certified and irrefutable reconstruction of past events. Valid as evidence in legal proceedings.
Tax authorities systematically challenge this evidence because of its obvious weaknesses.
They allow editing of past locations. They are not valid as expert evidence because there is no guarantee that the data has not been manipulated.
They don't prove your identity. It could be a family member or anyone else making purchases on your behalf. They don't prove physical presence.
GeoNotary solves this problem. We certify not only where you were, but also that it was you who was there, exactly when, and what you were doing.
The only system that simultaneously certifies the four dimensions necessary for irrefutable proof.
Proves where you were at every moment with GPS coordinates notarized on blockchain.
Identifies that you are carrying the phone through unique movement patterns. AI trained exclusively for you.
Date and time obtained from verified servers, not from the device, preventing possible manipulation. Immutable blockchain certification.
Proves what you were doing at that moment: walking, resting, in a vehicle.
Just focus on living your life. GeoNotary automatically certifies your location every day.
Install the app and allow location access. GeoNotary works in the background without you having to do anything else.
The app automatically notarizes your location on blockchain with verified timestamp. You just continue with your life.
If you receive a tax inspection, you already have the proof. Use your own lawyers or hire our legal assistance services and expert reports.
GeoNotary certifies your data automatically. You decide whether to use your own lawyers or hire our additional services.
Your subscription includes continuous certification and custody of all your location data with evidentiary validity.
In case of an inspection, we issue an official certificate confirming that we have your certified records. This document may be sufficient for the tax authority to discontinue the procedure.
If needed, we have legal assistance services and expert reports that you can hire independently:
Our reports use SHA-256 hash (Judiciary standard) and immutable blockchain certification.
The same standards used by the Judiciary.
Hardware-level cryptographic certification. Guarantees that data comes from a real device, not a simulator.
Artificial intelligence model trained only with your movement patterns. No one else can generate your data.
Date and time obtained from verified servers, not from the device, preventing possible manipulation.
The same algorithm used by the Judiciary to verify the integrity of digital documents.
Each record is notarized on blockchain. No one can edit, delete or manipulate the data once certified.
Optimized technology that works in the background without noticeable impact on your iPhone battery.
We have a specific application to demonstrate in court the effectiveness and absolute precision of our AI algorithm for recognizing movement patterns.
It is the main criterion for determining your tax residency. If you spend more than 183 days in a country, you are generally considered a tax resident there and must pay taxes on your worldwide income in that country.
Because we certify 4 dimensions: WHERE you were, WHO you were (that it was you and not someone else), WHEN exactly, and WHAT you were doing. Other evidence like tickets or cards only prove part of it and can be challenged.
No. We use Apple App Attest (hardware certification), timestamps from external servers, biometric AI and blockchain notarization with SHA-256 hash. It is technically impossible to falsify or edit the records.
You already have the certified proof. You can use your own lawyers with our data custody certificate. If needed, we also offer additional legal assistance services and expert reports with specialized expert witness.
Very little. The technology is optimized to record location efficiently without affecting your device's battery life.
Your historical data is safe on our servers. Install the app on the new device, restore your subscription and continue with certification. All your history remains intact.
Don't wait until you have problems with the tax authority. Start generating irrefutable proof from day one.
