This Privacy Policy describes how Spoolr ("we," "us," or "our") collects, uses, and protects your information when you use spoolr.net and any associated mobile applications (collectively, the "Service"). Spoolr is an independent, individually developed project.
By creating an account or using the Service, you agree to the practices described in this policy. If you do not agree, please discontinue use of the Service.
If you have any questions or requests, contact us at hello@spoolr.net.
We collect only the data necessary to provide the Service. The categories of data we collect are:
| Category | Examples | Why We Collect It |
|---|---|---|
| Account information | Email address, display name | To create and authenticate your account |
| Inventory data | Filament name, brand, material type, color, weight (total and remaining), print temperatures, purchase cost, date added | Core functionality — tracking your spool inventory |
| Usage & log data | Weight usage per print, inventory additions and reductions, cost consumed | Usage history, analytics, and cost tracking features |
| Photos | Spool label photos or custom spool images you upload | Visual identification; label scanning (optional, AI-powered) |
| User preferences | Currency preference, cost tracking on/off, theme | To personalize the Service to your settings |
| Subscription data | Subscription tier, billing period, Stripe customer ID | To manage your Pro subscription and feature access |
| Technical data | Browser type, IP address (server logs), error reports | Service reliability, debugging, security |
We do not collect payment card numbers, bank account details, or any sensitive financial information directly. All payment data is handled exclusively by Stripe (see Section 4).
We use the data we collect for the following purposes:
We do not use your data for advertising, behavioral profiling, or any purpose beyond what is listed above.
Your data is stored on Supabase, a managed cloud platform. Supabase infrastructure is hosted on Amazon Web Services (AWS).
We implement the following security measures to protect your data:
While we take security seriously, no internet transmission or cloud storage system is completely immune to risk. We encourage you to use a strong, unique password and to keep your account credentials private.
The Service integrates with the following third-party providers. Each provider has its own privacy policy governing how they handle the data they receive.
We select these providers carefully and only share data with them to the extent necessary to operate the Service. We do not share your personal data with any other third parties, advertisers, or data brokers.
We use browser storage mechanisms only for the purpose of operating the Service — not for advertising or cross-site tracking.
| Storage Type | What Is Stored | Purpose |
|---|---|---|
| Local Storage | Supabase authentication session token | Keeps you signed in between browser sessions |
| Local Storage | Theme preference (dark/light) | Remembers your display preference |
| Session Cookie | Stripe checkout state | Maintains checkout flow continuity during payment |
We do not use third-party tracking cookies or analytics cookies (such as Google Analytics). You can clear local storage and cookies at any time through your browser settings. Doing so will sign you out of the Service.
We retain your data for as long as your account remains active. If you request account deletion, we will permanently delete your account and all associated data — including your spool inventory, usage history, photos, and settings — within 30 days of your request.
Certain data may be retained for longer periods when required by law (for example, records related to financial transactions may be retained for tax and legal compliance purposes). Stripe retains payment records according to their own retention policies and applicable financial regulations.
You have meaningful control over your data. At any time, you may exercise the following rights by contacting us at hello@spoolr.net:
To exercise any of these rights, email hello@spoolr.net with a brief description of your request. We will respond within 30 days.
We do not sell, rent, lease, or trade your personal data to any third party under any circumstances. Your data exists solely to provide you with the Spoolr service.
We do not share your personal data with advertisers, data brokers, or marketing platforms. We do not use your data to build advertising profiles, and we do not participate in behavioral advertising networks.
The Service is not directed to children under the age of 13, and we do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at hello@spoolr.net and we will promptly delete the information.
If you are between 13 and 18 years of age, please review this policy with a parent or guardian before creating an account.
We may update this Privacy Policy from time to time to reflect changes in the Service, applicable law, or our data practices. When we make material changes, we will update the "Last updated" date at the top of this page.
For significant changes, we will make reasonable efforts to notify you — for example, by sending an email to your registered address or displaying a notice within the application. Your continued use of the Service after changes take effect constitutes your acceptance of the revised policy.
We encourage you to review this page periodically. Previous versions of this policy are available upon request.
If you have any questions, concerns, or requests related to this Privacy Policy or how we handle your data, please reach out:
We aim to respond to all privacy-related inquiries within 30 days. For account-specific issues, including data deletion requests, please include the email address associated with your Spoolr account.
