Data privacy basics every founder should know
Every product that handles user data carries a responsibility — and increasingly, a legal one. The good news is that good data privacy is mostly common sense applied consistently. Here are the basics every founder should know.
Collect only what you need
The simplest privacy principle is also the most powerful: don't collect data you don't need. Every extra field is a liability — something to secure, justify and potentially lose in a breach. Ask for the minimum that genuinely serves the user and the product.
Be transparent and give control
- Say what you collect and why, in plain language — a clear privacy policy people can actually understand.
- Get real consent where it's needed, and make it as easy to withdraw as to give.
- Let people access and delete their data. Users increasingly expect (and are entitled to) this.
Secure what you keep
Data you hold must be protected — encryption, access controls, and good security practice. A privacy promise means nothing if the data leaks. Treat security and privacy as two sides of the same responsibility.
The safest data is the data you never collected. Be minimal on purpose.
- Collect only the data you genuinely need.
- Be transparent, get real consent, and let users access and delete their data.
- Secure what you keep — privacy without security is empty.
Frequently asked questions
Does data privacy only matter for big companies?
No. Users and regulators expect good data practice from products of every size, and small companies are frequent breach targets. Good habits early are far easier than fixing problems later.
What's the easiest way to reduce privacy risk?
Collect less. Every piece of data you don't hold is one you can't lose, misuse, or have to protect and justify.
Do I need a privacy policy?
Yes — a clear, honest privacy policy is a basic expectation (and often a legal requirement) for any product collecting personal data.
