Bubble.io GDPR Compliance: What You Need to Build a Legally Sound App
GDPR applies if you have EU or UK customers, regardless of where your company is based. Six GDPR requirements that affect your Bubble app, the technical implementation for consent management, data access, and the right to erasure.
What Compliance Actually Means for SaaS Founders
The General Data Protection Regulation (GDPR) applies to any application that processes personal data of people in the EU or UK, regardless of where your company is based. If your Bubble SaaS has EU or UK customers, GDPR applies to you. Non-compliance risks fines up to €20M or 4% of global annual turnover, whichever is higher. This guide covers what GDPR requires at the product level and what you need to build in Bubble to achieve reasonable compliance.
What You Must Build
Privacy Policy
A clear, accessible Privacy Policy explaining: what personal data you collect, why you collect it (lawful basis), who you share it with (Bubble, Stripe, SendGrid, etc.), how long you keep it, and how users can exercise their rights. Link from your signup page, footer, and account settings.
Consent Collection
For marketing emails and non-essential cookies: collect explicit opt-in consent. Store consent with a timestamp on the User record: email_marketing_consent (yes/no), consent_timestamp (date). Do not pre-tick marketing opt-in boxes.
Data Subject Access Request
Users have the right to receive a copy of all personal data you hold about them within 30 days of request. Build a DSAR workflow: on request, generate a CSV or PDF of all records related to that user and email it to them.
Right to Erasure
Users have the right to request deletion of their personal data (‘right to be forgotten’). Build a deletion workflow: anonymise PII fields (name, email, phone) on all records related to the user. Do not delete records — anonymise them to preserve referential integrity.
Data Retention
Do not keep personal data longer than necessary. Define retention periods: inactive user data after 3 years, churned customer data after 2 years, support tickets after 1 year. Build scheduled workflows that anonymise expired data automatically.
Data Processing Agreement
Sign a DPA with Bubble (available in their enterprise plans and standard terms). Sign DPAs with Stripe, SendGrid, and any other processor that handles your users’ personal data. Store copies of signed DPAs.
The Technical Implementation
email_marketing_consent
: yes/no (default: no)
marketing_consent_at
: date
terms_accepted
: yes/no
terms_accepted_at
: date
privacy_policy_version
: text (e.g. ‘2026-01-01’)
// Set on signup; re-obtain if policy version changes
Step 1
: Create UserDataExport record
Step 2
: Schedule backend workflow ‘generate_user_data_export’
// Backend workflow: collect all records for this user
Search for [all data types with created_by = this User]
Format as CSV
+ upload to secure storage
Email user
: ‘Your data export is ready’ + download link
Link expires
: after 48 hours
Step 1
: Update User: name=’Deleted User’, email=’deleted@example.com’
phone=”, address=”
Step 2
: Update all records created_by this User:
Replace name/email fields with ‘Anonymised’
Step 3
: Update User: is_anonymised = yes, anonymised_at = now
// Records remain for audit/billing history; PII is gone
