Is it possible to record conversations on WhatsApp legally?

Before moving on to the technical part, let's deal with the legal side. In most countries, conversation recording permitted only with the consent of all participants. Exceptions:

• 📜 Russia: according to Art. 23 of the Constitution, recording is permitted without consent if you are a party to the conversation and are not distributing the recording publicly (for example, for personal use or legal proceedings).
• 🌍 EU and US: Most states/countries require notice to the second party (for example, the phrase “The conversation is being recorded”). In California or Germany, recording without consent may be considered a violation of the law.
• ⚖️ Other cases: if the conversation contains evidence of a crime, its recording can be used in court even without consent (but this is decided by the judge).

WhatsApp official prohibits recording conversations in your Terms of Use (clause 3.4). However, technically, the messenger cannot block your account for this - only if you distribute the recording publicly. Exception: WhatsApp Business accounts can keep a call log as part of the agreement with customers.

⚠️ Attention: If you plan to use the recording in court or to resolve a conflict, check your local laws for current regulations. The rules may change - for example, in 2023, in some countries, penalties for unauthorized recording have been tightened.
