Data, Logins, Security, and Privacy for No-Code Apps
Lesson 3: Collect Less, Protect More – Personal Data Basics
Lesson Objectives
By the end of this lesson, students should be able to:
- Remove unnecessary personal data fields.
- Write a retention and deletion plan.
- Recognize data that needs professional advice.
Lesson Content
- Collect less: every field you collect is something you must protect. Ask "will I use this in the next month?"
- Payments: use a payment provider's hosted checkout (such as Stripe) so card numbers never touch your app.
- Retention: decide how long to keep data and how to delete it (for example, "delete closed quote requests after 2 years").
- Requests: plan how you would export or delete one person's data if asked.
- Special data: health, children's, financial, or government ID data often carries legal duties; get qualified advice before collecting it.
- Laws vary: privacy rules depend on where you and your users are (for example, GDPR in Europe or state privacy laws in the United States). This course is not legal advice.
