Write the question before choosing a file
Write one sentence without personal data: “This page has the wrong tower name,” or “I cannot identify which services the fee includes.” If that and a public link explain the issue, there is no need to prove you are a resident by sharing private paperwork.
Identify the recipient’s actual task. Building management, a contract adviser and a website feedback form have different roles. A familiar logo or quick reply does not establish a need for your complete file.
List what the recipient does not need
Check personal names, identity numbers, contacts, signatures, account and transaction identifiers, and information tied to a private unit. Look for co-owners, guarantors and family members too. Possessing a document does not mean every other person’s information belongs in your message.
Work on a separate copy and preserve the original. A black rectangle is not necessarily deletion: ICO guidance warns that text covered by a shape can remain recoverable in an electronic file. Get help if you cannot prepare it safely.
Give photographs their own check
Before using a photograph to explain a location error, inspect faces, plates, QR codes, name boards, mail and phone screens around the subject. A wide view can disclose more than your question requires. If you cannot isolate the useful information, use a written description or suitable public source.
Check accompanying information such as filenames and location metadata, not just the visible image. Vietnam’s government explainer recognises location information as potentially personal. A project-name correction does not require your home coordinates or routine.
Use a suitable channel for genuine document work
If a qualified professional needs documents for an agreed task, ask which pages are necessary, who can access them, how to send them and what handling policy applies. Verify the destination through an independently known channel. A large group chat is not private consultation.
Separate the question summary from sensitive files and record what you sent and to whom. If sent incorrectly, promptly contact the recipient or platform about limiting further disclosure. A deletion request is not proof that every copy has disappeared.
Give HAVO useful feedback without private files
For a content correction, identify the page, disputed wording, any public source and what needs clarification. HAVO feedback and data-report forms are not channels for identity documents or private files. Do not paste a contract into a text field as a substitute for an attachment.
Before sending, ask: right recipient, necessary detail, identifiable person, public-link alternative? If answering requires your private contract, move to an appropriate professional channel rather than adding more personal data to feedback.
Words worth knowing
- Disclosure copy
- A separate version prepared for a defined purpose, distinct from the retained original.
- Metadata
- Information about a file that may exist beyond its visible content and needs checking before sharing.
Take this to a viewing
- Confirm recipient and purpose.
- Remove unnecessary personal information.
- Prefer a written explanation and public source.
Common questions
Is a contract safe to share once names are covered?
Not necessarily. Other identifiers, people and hidden information remain possible; first ask whether the contract needs sharing at all.
Does this guide promise a fixed deletion date at HAVO?
No. It makes no document-retention or deletion guarantee. Read the current policy and keep private files out of feedback.
