What retention is, why it matters, how to build a retention schedule and how to put it into practice in an app.

Quick answer
Data retention is the policy of deciding how long each kind of information is kept, where it is stored and what happens at the end. A retention schedule lists each record type, the reason to keep it, the source of the requirement, the period, the owner and the end action (delete, anonymise or archive). Periods are set by law, regulators, insurers and contracts and vary by country and profession, so take advice. Build retention into apps with dates, scheduled workflows and deletion and export support.
Key takeaways
- Retention periods vary by country, profession, regulator, insurer and contract; take advice.
- Data protection laws expect personal data not to be kept longer than necessary.
- Schedule: record type, reason, source, period, owner, end action, review date.
- Plan for backups, logs and legal holds.
- Build retention dates and scheduled workflows into the system.
In this guide
This guide is general information, not legal advice. Retention periods are set by law, regulators, insurers and contracts, and they vary by country and profession. Take advice for your situation.
What is data retention?
Data retention is the policy and practice of deciding how long different kinds of information are kept, where they are stored and what happens when the time is up. A retention schedule is the document that sets this out record type by record type. Good retention means keeping what you must for as long as you must, and disposing of the rest securely.
Why does retention matter?
- Legal and regulatory duties require certain records to be kept for set periods.
- Data protection laws such as the GDPR include a storage limitation principle: personal data should not be kept longer than necessary for its purpose.
- Risk. Data you no longer need still has to be secured and can be breached or disclosed.
- Cost and clutter. Old data makes systems slower and harder to manage.
- Disputes. Records may be needed to answer claims.
What does a retention schedule look like?
| Record type | Example reason to keep | Typical approach |
|---|---|---|
| Client engagement records | Professional duties and potential claims | Retain for the period set by regulator and insurer, then review and dispose |
| Financial and tax records | Legal and tax requirements | Retain for the statutory period |
| Client identity and due diligence records | Anti-money-laundering or similar rules where they apply | Retain for the period the rules require after the relationship ends |
| Enquiries that did not become clients | Short-term follow-up only | Delete or anonymise after a short, defined period |
| Marketing and consent records | Proof of consent | Retain while the consent is relied on, plus a defined period |
| Staff records | Employment law and payroll | Retain as law requires |
| Audit logs | Security and accountability | Retain for a defined period |
| Backups | Disaster recovery | Rotate according to a schedule, so deleted data eventually leaves backups |
The periods are deliberately not given here. They differ by place and profession. Ask your regulator, insurer or adviser, and record the source of each period.
How do you build a retention schedule?
- List your record types. What information do you hold?
- Identify the reasons to keep each. Law, regulation, contract, insurance, business need.
- Set a period for each, with the source recorded.
- Decide the end action: delete, anonymise or archive.
- Assign an owner for each record type.
- Handle exceptions, such as a legal hold when a dispute or investigation requires keeping records beyond the normal period.
- Review annually and when rules change.

How do you put retention into practice in an app?
- Record the dates that start each retention clock, such as engagement end date.
- Build scheduled workflows that flag or remove records at the end of their period, with a human check where needed.
- Support deletion and export for individual data requests.
- Include retention in the data model from the start, so records can be separated by type.
- Plan for backups and logs, which also hold copies.
- Document what was deleted and when.
See database design mistakes, our security guide and what maintenance involves. Retention requirements belong in the PRD, and our Discovery Sprint ($345, delivered in 24 hours, credited toward the build) covers them. Builds start at $3,500.
What mistakes should you avoid?
- Keeping everything forever.
- Deleting records that must be kept.
- Having no owner for retention decisions.
- Forgetting backups, exports and email copies.
- No process for legal holds.
- Retention rules written down but not built into systems.
