What a buzzer app knows about you, and why it is worth more than you think
A buzzer app holds the phone number of every adult in your home, your building address and unit, and a log of each time your door was opened. Together that says who lives where, how to reach them and when they are usually out. BuzzMeBro keeps only what the door needs, records no audio, and never sells any of it.
Most people pick a buzzer app the way they pick a phone case. It is a small monthly charge, it makes the door work, and nobody reads anything. That is reasonable for a phone case. A buzzer service is a different kind of object, because of what it has to know to do its job.
What every buzzer service has to collect
None of this is sinister. A buzzer service cannot ring your phones without knowing them. The list is about the same for every service on the market, BuzzMeBro included.
| What it holds | Why it needs it | What it tells somebody else |
|---|---|---|
| The phone number of every person on the door | Those are the phones it rings | Who lives together, and how to call or text each of them |
| Your building address and unit | So a visitor reaches the right apartment | Exactly where those people sleep |
| A log of each buzz | So you can see who opened the door | When the home is usually empty, and how often you get visitors |
| Payment details | To charge the subscription | A real name and a billing postal code |
Read the right-hand column on its own. A list of adults, their mobile numbers, their home address down to the unit, and the hours the place is empty. Very few apps on your phone hold all four of those at once.
Who wants a phone number tied to an address
There is an established market for exactly this. The US Federal Trade Commission studied nine data brokers in 2014 and found one that held 700 billion data elements. Matching a mobile number to a name and a street address is one of the basic products that industry sells.
It is also cheap. Researchers at Duke University bought records from brokers in 2023 and paid as little as 12.5 cents each for a name, a home address, an email and a mobile number. Nobody gets rich off one record. The money is in holding a few hundred thousand of them.
Canadians already sense this. In the federal Privacy Commissioner’s latest national survey, 92% said they were concerned about their personal data being sold or shared with third parties, and 88% were concerned about it being used to train AI systems.
Collection is not the problem. Permission is.
Since every buzzer service holds roughly the same things, the difference between them is what each one has given itself permission to do next. That lives in the privacy policy, and it is where the services stop looking alike.
- Does the policy say the data is never sold? Some say it in an FAQ and leave it out of the policy, which is the document that counts.
- What happens if the company is sold? Several buzzer apps state that user information is an asset that transfers to whoever buys them. Here is how that clause works.
- Does the site run advertising trackers? A Meta Pixel on a service that knows your address is a choice somebody made.
- Does it say anything about AI? Most say nothing at all, which leaves the question of AI training open.
You can check all four in about five minutes. This is the exact method, with the words to search for.
What BuzzMeBro holds, and what it has ruled out
BuzzMeBro holds the same core list, because the door needs it: the phone numbers on your resident list, your postal code, unit and building address, and a log of each buzz. It does not record call audio, does not store who was at the door, does not track your location and runs no advertising trackers.
The part that differs is written into the privacy policy. Your data is never sold, rented, licensed or traded. It is never used to train AI, by BuzzMeBro or by anyone it is handed to. If the company is ever bought, your data is deleted before the sale, so a buyer never gets it.
That is why BuzzMeBro costs $9.99 a month for the apartment. The subscription is the only thing the business is paid for, and a Toronto company that has put that in writing can be held to it. See how the named services compare.
Questions people ask
Is it safe to give a buzzer app my phone number and address?
It is as safe as the service’s privacy policy makes it. Every buzzer service needs your number and your unit to work. What varies is whether the policy lets that information be shared with partners, used for advertising, or transferred when the company is sold. Read those three parts before you sign up.
Do buzzer apps record my calls?
It depends on the service, so check its policy. BuzzMeBro bridges the call between the lobby panel and your phones and captures no audio at all. Its log records when a buzz happened and who opened the door, never what was said.
Can a buzzer app see who visits me?
A lobby panel calls from the building’s line, so a buzzer service normally sees a call from the building rather than the visitor’s own phone. It still learns when you get visitors and how often. BuzzMeBro’s log stores the time and the outcome and no visitor identity.
Does BuzzMeBro sell my data?
No. BuzzMeBro’s privacy policy says your personal information is never sold, rented, licensed or traded, is never used to train AI models, and is deleted before any sale of the company, so a buyer never gets it. The subscription is the only thing BuzzMeBro is paid for.
