Privacy Policy – SpoolVault

Last updated: February 2026

SpoolVault is developed and operated by Three19 Pty Ltd (“we”, “us”, “our”), which is the data controller for the processing described in this policy.

We respect your privacy and are committed to handling your information transparently and responsibly.

SpoolVault is available to users worldwide. This policy is intended to apply to all users, wherever they are located.

This Privacy Policy explains what information SpoolVault collects, how it’s used, and your rights under applicable privacy laws, including Australian privacy law.

1. Overview – A local-first app

SpoolVault is designed as a local-first application. Most of your filament inventory and usage data is stored on your device, not on our servers.

We do not require users to create an account, and we do not collect names, passwords, or email addresses within the app itself.

2. Information we collect

a) Information stored locally on your device

The following information is stored locally on your device:

Filament inventory and quantities
Print usage data
Colour selections
App preferences

This data remains on your device unless you explicitly choose to export or share it.

b) Anonymous analytics and feature data

To improve SpoolVault, we collect limited, anonymous data via Supabase:

Anonymous app usage events (e.g., basic feature interactions and screen usage events)
Colour submissions when you add custom filament colours (brand, type, colour name, hex value)
An anonymous user identifier (UUID generated on your device)
A device-scoped identifier provided by the operating system (IDFV), used only to prevent duplicate or abusive colour submissions
App version and basic diagnostic metadata

This data:

Is not linked to an account
Is not linked to your personal identity
Is used solely to improve app functionality and colour data accuracy

SpoolVault does not track users across apps or websites owned by other companies.

c) Subscriptions and purchases

SpoolVault offers optional paid subscriptions, which are processed by Apple and managed via RevenueCat.

We receive limited subscription-related information, such as:

Whether a subscription is active
Subscription product identifiers

We do not receive or store:

Payment card details
Billing addresses
Apple ID information

d) Support communications

If you contact us via email, we may collect:

Your email address
The content of your message

This information is used only to respond to your enquiry and provide support.

3. IP addresses

We do not aim to collect or store your IP address in our own systems.

However, IP addresses may be processed by Apple, RevenueCat, and Supabase as part of normal network communications, security logging, and fraud prevention.

4. How we use information

We use collected information to:

Operate and maintain the app
Improve features and usability
Maintain accurate filament colour data
Manage subscriptions
Provide customer support
Ensure app security and stability

EU/UK users – legal bases for processing

For users in the European Union or United Kingdom, we rely on the following legal bases to process personal data:

To operate and provide the app and manage subscriptions: performance of a contract (Art. 6(1)(b) GDPR).
To improve features, maintain app security, and analyse anonymous usage data: our legitimate interests in operating and improving SpoolVault (Art. 6(1)(f) GDPR).
To respond to support enquiries: performance of a contract or legitimate interests, depending on context.

5. Third-party service providers

SpoolVault uses the following third-party services:

Apple App Store & In-App Purchases
RevenueCat (subscription management)
Supabase (anonymous analytics and data submissions)

These providers process data in accordance with their own privacy policies:

Apple: https://www.apple.com/privacy/
RevenueCat: https://www.revenuecat.com/privacy/
Supabase: https://supabase.com/privacy

6. International data processing

Our service providers may process data in Australia, the United States, or other countries where they operate infrastructure.

We take reasonable steps to ensure these providers handle information in line with applicable privacy laws.

For users in the United States, including California, our current data practices do not involve selling or sharing personal information for cross‑context behavioural advertising. If local privacy laws grant you additional rights, you can contact us and we will do our best to assist you.

7. Data retention

Anonymous analytics and submission data is retained only for as long as necessary to improve the app and maintain data integrity, after which it may be deleted or anonymised further.

Support emails are retained only as long as required to resolve enquiries.

8. Your rights

You may contact us to:

Ask questions about this policy
Request access to personal information we hold about you
Request correction or deletion of information where reasonably possible

Because SpoolVault does not use accounts, some rights (such as data portability) may be limited to information you voluntarily provide, such as support emails.

If you are located in the European Union or United Kingdom, you may also have additional rights under applicable data protection laws, including the right to object to certain processing, and the right to lodge a complaint with your local data protection authority.

9. Privacy complaints (Australia)

If you have a privacy complaint, please contact us at:

Email: privacy@three19.com.au

We will acknowledge your complaint and aim to resolve it within 30 days.

If you are not satisfied with our response, you may contact the Office of the Australian Information Commissioner (OAIC).

10. Children’s privacy

SpoolVault is not directed at children under 13, and we do not knowingly collect personal information from children.

If you believe a child has contacted us and provided personal information via email, please contact us and we will delete that information where reasonably possible.

11. Changes to this policy

We may update this Privacy Policy from time to time. The latest version will always be available within the app or on our website.

Continued use of SpoolVault after changes means you’ve reviewed the updated policy.
