Automated COPPA & FERPA Data Deletion: A Simple Guide for AWS and GCP
How to automatically delete children's and student data on time — built with AWS and GCP

If your platform stores data from children or students — think edtech apps, school tools, or online classrooms — you can't just keep that data forever. The law says you have to delete it once you don't need it anymore. Doing this by hand is slow and easy to mess up. This guide shows you how to set up a system that deletes the data automatically, on a schedule, using AWS or GCP.

Why This Matters
Two U.S. laws control this:

COPPA says companies can't keep personal data from kids under 13 longer than needed. Once you're done using it, you have to delete it safely.
FERPA protects student records. Schools and companies must control who sees this data and must delete it properly once it's no longer needed.
Doing this deletion by hand is risky — people forget, make mistakes, or can't prove it happened. Automating it with cloud tools solves that problem, and gives you proof (logs) that you followed the rules.

What the Law Requires Before you build anything, know the rules you're building for.

COPPA basics

Don't store kids' data forever — decide how long you need it, and write that down.
When you delete it, make sure it's actually gone and can't be recovered by anyone unauthorized.
Get parent permission before using the data, and follow the FTC's newer rules about AI-created profiles.
FERPA basics

Schools and companies must stay in control of student records at all times.
Delete or return records once you don't need them, or once your contract with a school ends.
Don't use student data for ads or to train AI models unless you have permission.
Keep a record (audit trail) showing what happened to the data.
General good habits

Encrypt data (AES-256 when stored, TLS 1.3 when it's moving between systems).
Only let the right people access the data.
Keep logs for at least 3 years so you can prove what happened.
If there's a lawsuit or investigation, pause deletion for the data involved (a "legal hold").
How long to typically keep things

Data Type How Long to Keep It
Account info (after account closes) 30–90 days
Homework / assignment records 1–2 years
Activity logs 30–90 days
Audit logs (your deletion records) At least 3 years

The Basic Setup (4 Steps) Every good deletion system does these four things:

Find and label the data — figure out what data you have, who it belongs to, and how long you're allowed to keep it.
Set the rules — tell your cloud storage and databases how long to hold each type of data.
Delete it automatically — use automated tools to remove the data everywhere it lives (main storage, backups, everywhere).
Check and record it — confirm the deletion worked, and keep a log as proof.

Setting This Up on AWS Step A — Delete files automatically (S3)

In your S3 storage bucket, go to Management → Lifecycle Rules. You can tell AWS to auto-delete files after a set number of days. For example:

Student file uploads → delete after 180 days.
Temporary log files → delete after 30 days.
Anything under legal review → lock it so it can't be deleted until the hold is lifted.
Here's what that setup looks like in code:

{
"Rules": [{
"ID": "COPPA-student-data-180d",
"Filter": { "Prefix": "student-data/" },
"Status": "Enabled",
"Expiration": { "Days": 180 },
"NoncurrentVersionExpiration": { "NoncurrentDays": 30 }
}]
}
Step B — Delete data from your databases

For databases like RDS/Aurora: schedule automatic cleanup jobs.
For DynamoDB: turn on "TTL" (time-to-live) — it deletes rows automatically once they expire, no extra code needed.
For large data lakes: use a tool called "S3 Find and Forget" to locate and remove one person's data — handy when someone specifically asks you to delete their info.
Step C — Keep proof it happened

Use AWS Step Functions to run the full cleanup process in order: delete from the database → delete files → delete backups → save a log saying it worked.
Use CloudTrail and CloudWatch to record every deletion, and store those logs somewhere separate and secure.

Setting This Up on GCP Step A — Delete files automatically (Cloud Storage)

Go to your bucket → Lifecycle → Add Rule. You can delete files based on age, name, or label. For example: delete child account files after 90 days, but give yourself a 7-day safety window in case something was deleted by mistake.

Here's what that setup looks like using Terraform:

resource "google_storage_bucket" "edu_data" {
name = "school-records-secure"
location = "us-central1"
uniform_bucket_level_access = true

lifecycle_rule {
condition { age = 180, matches_prefix = ["student-submissions/"] }
action { type = "Delete" }
}

soft_delete_policy { retention_duration_seconds = 604800 }
}
Step B — Delete data from your databases

BigQuery: set tables or partitions to expire automatically, or run scheduled cleanup jobs.
Cloud SQL / Firestore: use Cloud Functions to check dates and delete old records.
Backups: apply the same delete-after-X-days rule to your backup storage too.
Step C — Keep proof it happened

Cloud Audit Logs record every deletion — export these logs somewhere with a fixed storage period.
VPC Service Controls stop data from leaving your system without permission, and Access Transparency shows that even Google's own staff can't see your data without approval.

Best Practices to Follow Write your retention policy first. COPPA requires you to have a written policy that says exactly what you keep and for how long. Label everything. Tag your data (e.g., "COPPA," "keep for 90 days," "student record") so your automated rules know what to do with it. Respect legal holds. If data is part of a legal case, never delete it — pause the process until the hold is lifted. Delete it everywhere, not just hide it. Make sure backups and cached copies are gone too, not just the main file. For very sensitive data, you can also destroy the encryption key — this makes the data unreadable even if a copy exists somewhere. Test it regularly. Run practice deletions, check that nothing was missed, and review your logs every month. Update your contracts. If you work with schools, your contract should say you'll delete their data within 30–90 days of them asking or the contract ending. Conclusion Automatically deleting data isn't just a technical task — it's how you prove you follow the law and respect people's privacy. AWS and GCP already give you the tools you need: automatic deletion rules, expiration timers, and detailed logs. Once you set this up properly, you spend less time on manual cleanup and worry less about compliance risk.

You don't want to be the company that says "we forgot to delete it." With a system like this in place, you can tell parents, schools, and regulators with confidence: we only keep what we need, and we delete it safely when we're done.
