Apartment buzzer data: a privacy & vendor checklist

By Protobuzz · Published December 20, 2025 · Updated October 16, 2026

If a resident asks, “Can you see when my visitors arrive?”, could your building give a precise answer? That is a useful starting point for reviewing buzzer privacy.

Ask your provider to show you a sample record with personal details removed. Depending on the system, it might contain a unit number, phone number, call time, access decision or recording. Check which of those your setup actually stores. A feature list cannot tell you what is enabled in your account.

This checklist is for Canadian building managers reviewing a buzzer service. Which privacy law applies depends on the organization and its activities; federal and provincial rules can differ. The Office of the Privacy Commissioner of Canada explains those distinctions in its guide to provincial laws and PIPEDA. Use the questions below to gather evidence for your building's review, rather than treating the checklist as a compliance certificate.

Follow one test call through the system. Look at the resident app, the building's admin account and any export or email it creates. Ask the provider what it keeps separately for support, telephony and backups.

• Which fields are saved, and what is each one used for?
• Are calls recorded, or is only call activity logged?
• Where is the data processed and stored? Which other companies handle it?
• Does staff download it into spreadsheets, ticketing tools or email?

Write down the answer beside each location. An export sitting on a former manager's laptop still needs attention even if the vendor has deleted its copy.

Ask what question an access log needs to answer and how far back that question reasonably goes. Then document the retention period for that purpose, who approved it and how deletion happens. Check backups and downloaded copies separately.

There is no retention period supplied by this checklist. Under PIPEDA's limiting use, disclosure and retention principle, personal information should be kept only as long as needed for the identified purposes. The regulator's retention and disposal guidance covers how to develop a policy. Check applicable recordkeeping obligations before choosing your building's period.

If records must be preserved for a particular dispute or investigation, document which records are covered and who will review the hold. Do not let one incident silently turn into indefinite storage of everyone's history.

Sign in with the roles your team actually uses. Can a concierge view every unit's history? Can a temporary contractor download it? Can someone who only needs to answer calls also change guest permissions?

Give each person their own account where supported, remove former staff and request multi-factor authentication for admin access. Verify whether the provider supports these controls on your plan. Ask whether it records permission changes and exports, and whether your building can inspect those records.

For the privacy basis, the Canadian regulator's guidance on safeguards includes limiting access to people who need the information. The account checks here are practical ways to examine that access; they are not a claim that every buzzer vendor offers the same settings.

Use a test account, not a resident's live account. Ask the provider to show what happens when someone leaves:

1. Revoke their ability to answer calls, grant entry and manage guests.
2. Check linked household members, guest credentials and integrations.
3. Identify which profile details and historical records remain, why they remain and when they are deleted.
4. Explain what happens to backup copies and any exports held by the building.

Disabling entry and deleting personal information are separate tasks. Get both answers in writing, including any records the provider must retain. Test this again when you change providers or make a substantial account change.

Send the vendor these questions alongside any required data-processing agreement. Include Protobuzz if we are on your shortlist:

• Who can access our residents' data within your company, and for what work?
• Which service providers handle it, and how will you notify us if that list changes?
• What happens when we request an export, a correction or a deletion?
• Whom do we contact about a suspected exposure, and what notification commitments are in the contract?
• When our contract ends, how do we retrieve necessary records and confirm what you have deleted?

Keep the answers with the signed agreement and the date of your review. Where a feature is essential, request a demonstration or written confirmation for the plan you intend to buy.

Once you have checked the system, write a short notice stating what the building collects, why, who can view it, how long it is kept and whom residents can contact with a privacy request. Describe what you verified. Avoid promising that all data disappears at move-out if backups or required records remain.

For the board's review, keep a redacted sample record, the retention decision, the staff access list, the vendor's answers and the result of your move-out test. Assign someone to resolve unanswered questions before renewal. That gives the next manager something concrete to check when staff or settings change.

If this review is part of replacing your service, the buzzer app switching guide covers the directory change and guest handoff. Keep those entry tests alongside the data review: a working door and a documented privacy process answer different questions.
