Privacy Policy

Effective date: 1 July 2026

Tailor Base Patterns operates the website at tailorbasepatterns.com (the “Service”). This policy explains what data we collect, why we collect it, and your rights regarding that data.

1. Data we collect

Account data

When you register, we store your email address and a securely hashed password via Firebase Authentication. We use this solely to identify your account and send essential transactional emails (email verification, password reset).

Measurement data

You may save named sets of garment measurements (e.g. bust, waist, hip circumferences in centimetres). These figures describe abstract clothing dimensions and are not biometric data — they are not used to identify you as a natural person and are not shared with third parties. They are stored in your account solely to let you re-use them for future pattern generations.

Payment data

Payments are processed by Stripe. We never see or store your card number, expiry date, or CVC. We store only the Stripe session ID and the number of credits granted, which we need to fulfil your purchase and prevent duplicate credit grants.

Usage data

We log each pattern generation (garment scope, output formats, credit tier, and timestamp) under your account. This log is used to investigate support requests and detect abuse. We do not use it for advertising or sell it to third parties.

Technical data

Our servers receive your IP address and standard HTTP headers as part of every request. We do not build profiles from this data and it is not retained beyond normal server log rotation.

2. How we use your data

To create and manage your account.
To generate sewing patterns based on your input.
To process payments and grant credits.
To send transactional emails you explicitly requested (verification, password reset).
To detect and prevent fraud or abuse.

We do not send marketing emails, and we do not use your data for automated decision-making or profiling.

3. Legal basis (GDPR)

If you are located in the European Economic Area, our legal bases are:

Contract performance — processing your email address and payment records to provide the Service you signed up for.
Legitimate interests — generation logs and technical data for security and abuse prevention, balanced against your privacy interests.
Consent — where you voluntarily save measurement sets; you can delete them at any time.

4. Third-party services

Service	Purpose	Data shared
Google Firebase	Authentication & database	Email address, account data
Google Cloud Storage	Pattern file storage	Generated PDF/SVG files
Stripe	Payment processing	Email address, payment details
Google (Gmail)	Transactional email	Email address

Each provider has its own privacy policy and processes data under data processing agreements where required by law.

5. Data retention

Account and measurement data is retained for as long as your account is active. You can delete your account and all associated data by contacting us at the address below.

6. Generated pattern files

Pattern files (PDF, SVG) generated for paid users are uploaded to Google Cloud Storage and accessible via a time-limited signed URL.

7. Your rights

Depending on your location you may have the right to:

Access the personal data we hold about you.
Correct inaccurate data.
Request deletion of your account and data (“right to be forgotten”).
Restrict or object to certain processing.
Receive your data in a portable format.

To exercise any of these rights, email us at tailorbase.app@gmail.com. We will respond within 30 days.

8. Cookies

We do not use tracking or advertising cookies. Firebase Authentication uses browser storage (IndexedDB / localStorage) to maintain your session. No third-party advertising or analytics cookies are set.

9. Children

The Service is not directed at children under 16. We do not knowingly collect data from anyone under 16. If you believe a child has provided us with personal data, contact us and we will delete it promptly.

10. Changes to this policy

We may update this policy from time to time. The effective date at the top of this page will reflect any changes. For material changes we will notify you by email if we have your address on file.
