How to Document Harassment Safely and Responsibly

When someone is harassing you, keeping a clear record can help you get it to stop — but doing it the wrong way can put you at legal or physical risk. This is a careful guide to documenting harassment responsibly, with your safety first.

Important: This is general information, not legal advice. BlackBox is a personal recording tool — not a safety, security, or legal-evidence service — and you must never rely on it as your only protection or only record. Recording someone without the consent your jurisdiction requires can be illegal and can backfire. If you are in immediate danger, contact your local emergency services now. For abuse, stalking or threats, reach out to the police and to a specialised support service — and be aware that a recording discovered by the other person can escalate the situation.

Three golden rules

1. Safety before evidence. No recording is worth increasing your risk. If documenting could be discovered and provoke someone dangerous, get professional help first.
2. Stay lawful. Recording without required consent can be a crime and is often useless as evidence anyway — see recording consent laws and can audio be used as evidence?.
3. Never tamper. Keep originals factual and unedited; altered records lose all credibility.

Keep a dated, factual log

A written incident log is the backbone of any record and carries the least risk:

• When — date and time of each incident.
• What — exactly what was said or done, in neutral language.
• Where — location or platform.
• Who — anyone who witnessed it.
• Impact and actions — how it affected you, and any reports you made.

Record entries as soon as you safely can, while memory is fresh.

Preserve what already exists

Often the strongest documentation is already there:

• Messages, texts, emails, DMs — save and back them up.
• Screenshots with visible dates and usernames.
• Photos of anything relevant (notes, damage, etc.).
• Call logs and timestamps.

Recording — only where it's lawful and safe

Audio can play a role, but only if it's legal where you are and doesn't put you at risk:

• Confirm your area's consent rules first.
• Consider whether the other person could discover the recording and react dangerously.
• If you're unsure, a written log plus saved messages is usually safer and just as valuable.

If recording is lawful and safe in your case, capture it discreetly and keep the original untouched — see discreet voice recording, which also explains why your phone always shows a recording indicator.

Store everything securely

Keep your documentation where the other person can't reach it:

• Use a device and accounts they don't have access to.
• For any audio, keep it on-device and private — BlackBox stores recordings locally with no upload and a Face ID lock (see the privacy policy).
• Back up to storage you control, in case your device is lost or taken.

Get real help — don't go it alone

Documentation supports action; it isn't action by itself:

• Police for threats, stalking, or anything criminal.
• A lawyer for your options and to advise before you record or act.
• Specialised support services and hotlines for harassment, abuse, or domestic situations.
• Your employer or platform where relevant (see documenting workplace harassment).

The limits — please internalise this

BlackBox is not an emergency service and cannot protect you, contact anyone, or guarantee a recording is lawful or usable. Never treat it as your safety plan. The app can quietly keep a private, on-device record if recording is legal and safe in your situation — that's the extent of it.

The bottom line

Document harassment with a careful, dated written log and preserved messages; record only where it's lawful and safe; store everything securely and unedited; and get help from the police, a lawyer, and specialised services. A recorder like BlackBox can support that record privately — but your safety and proper professional help always come first.
