Law Enforcement Guidelines

Last updated: 28 October 2026

These guidelines are for police, prosecutors and other authorities who need information about a OneMessage account. OneMessage is run by Andreas Chouliaras, Ioannina, Greece. Users: please read our Privacy Policy instead.

How to send a request

• Email hello@getonemessage.com from an official address, with the subject "Law enforcement request".
• Include the requesting authority, the officer's name and contact details, the legal basis (for example a prosecutor's order or court order), and the case reference.
• Identify the account as precisely as you can: the mobile number used to sign up, the first name shown in the app, and the dates involved.
• Describe the information you need and the time period.

When we disclose information

We disclose user data only when the law requires it, for example in response to a valid order from a Greek or EU authority, or under an applicable international legal assistance procedure. We check every request before responding and disclose only what the request covers. Requests from outside the EU must go through the appropriate legal channels.

Emergencies

If there is an immediate risk of death or serious injury, write "EMERGENCY" in the subject line and describe the danger. We may disclose the information needed to prevent harm without a formal order, as data protection law allows. A formal request should follow.

What we may have

• Account details: mobile number, first name, date of birth, profile photos, and when the account was created.
• First messages, chats and photos sent in chats, with the time each was sent.
• Reports made by or about the account, and blocks.
• For Plus subscribers: which plan they have and when it started. Card details are held by the payment provider (Apple, Google or Stripe), not by us.

How long we keep it

• While the account exists, we keep its data.
• When an account is deleted, we keep a minimal record (mobile number, email address, first name, date of birth, creation and deletion dates) and a locked copy of its first messages and chats for 12 months, for safety reports and valid legal requests.
• Conversations saved with a report are kept for 12 months after the report is resolved.
• To make sure evidence is kept while you obtain a formal order, you can ask us to preserve a specific account's data. We keep it for 90 days, and longer if you renew the request.

Child safety

We report confirmed child sexual abuse material to the relevant authorities. See our Child Safety Standards.

Notifying users

We don't tell a user about a request concerning their account if the authority tells us that doing so is prohibited by law or would harm an investigation.
