What to Check Before You Sign Up to Anything Online
A five-minute check before you create an account prevents most of the regrets that come later.
Before the form
- Find the privacy policy and the terms, and confirm they open and are dated.
- Check who runs the service: a company name, a country, a way to contact a human.
- Decide what you are willing to give. An email alias and a strong, unique password are a good default.
During sign-up
- Read the checkboxes. A pre-ticked box that opts you into marketing is worth unticking.
- Give the minimum the form truly requires. Fields marked optional can stay blank.
- Watch for a second step that bundles consent for unrelated things into one button.
Watch for nudges
A dark pattern is a design that pushes you toward a choice you might not make freely, such as a bright "Accept all" button next to a greyed-out "Manage". Recognising the nudge is most of the defence against it.
Decide what the service does not need
A sign-up form often asks for more than the service requires to work: a phone number, a date of birth, a home address. Treat each field as a request you can decline unless it is genuinely needed, and give the least that still lets you use the thing you came for. Data you never hand over cannot later be leaked or sold.
After you are in
- Open the privacy or notification settings and turn off what you do not want.
- Note any free trial that becomes a paid plan, and set a reminder before it does.
Think about leaving before you join
The easiest moment to check how an account closes is before you open it. Look for how to delete the account and what happens to your data afterwards: is it erased, kept for a period, or merely deactivated? A service that explains deletion clearly tends to be one that handled your data carefully in the first place.
Give an address you can retire
Using a dedicated email alias for sign-ups keeps marketing and any future breach away from your main inbox, and it tells you which service leaked your address if spam starts arriving. Pair it with a unique password stored in a manager, so that one compromised account never becomes a key to the others.
Signing up is quick by design. Closing an account is often slower, so it is worth a moment of care at the start.
