Privacy

What this policy covers

Filamental ("we", "us", or "our") is a desktop application that you download and run locally on your computer. This Privacy Policy explains how we handle information when you use Filamental.

Our core commitment: We designed Filamental to respect your privacy and data sovereignty. We do not want your data, we cannot see your files, and we have no interest in monetising your information.

Information we DO NOT collect

Filamental does not collect, store, or transmit:

• Your flowchart designs, notes, or any content you create

• Your file names, folder structures, or file contents

• Your usage patterns within the app (keystrokes, features used, time spent, etc.)

• Screenshots, recordings, or any media from your computer

• Any personal documents, browsing history, or system information beyond what is listed below

We have no cloud storage, no analytics SDKs, no advertising trackers, and no telemetry. Your work stays on your computer, under your control.

Information we DO collect (very limited)

1. License validation data (required for subscriptions)

To ensure that your subscription is active and to prevent unauthorised use, Filamental periodically connects to Lemon Squeezy's license validation servers (typically once every 7 days). When it does so, the following information is transmitted:

• Your license key (a unique identifier for your purchase)

• A randomly generated installation ID (created when you first install the app)

• The current timestamp of the validation request

No design files, no personal content, and no identifiable user information (like your name or email) are transmitted – unless the license key itself is considered personally identifiable, which it generally is not.

This validation data is processed by Lemon Squeezy's servers (not by us directly) to confirm that your subscription is paid and active. We may access aggregated logs (e.g., number of active licenses) but we do not routinely review individual validation records.

If your subscription is terminated for any reason, Lemon Squeezy will retain validation records for up to 12 months for fraud prevention, after which they are deleted.

2. Payment and transaction information

When you purchase a subscription, you are redirected to Lemon Squeezy, our payment processor. Lemon Squeezy collects information necessary to process your payment, which may include:

• Your name

• Your email address

• Your billing address

• Payment method details (credit card, PayPal, etc.)

We do not receive or store your full payment details. Lemon Squeezy shares with us only your email address and a license key (and, if applicable, your name) to enable us to provide support and manage your license.

For details on how Lemon Squeezy handles your data, please review their privacy policy: https://www.lemonsqueezy.com/privacy

3. Information you voluntarily provide to us

If you contact us for support (via email, our website contact form, or other means), we will receive whatever information you choose to provide, such as:

• Your email address

• Your name (if you provide it)

• Any screenshots, descriptions, or files you attach to help us resolve your issue

We keep these communications private and only use them to assist you. We do not add you to any marketing lists unless you explicitly opt in.

4. In-app notifications (optional)

Filamental may occasionally display in-app notifications (e.g., about updates, new features, or important announcements). These notifications are generated locally and do not require any data to be sent to us. You can interact, dismiss or disable them.

How we use your information

We use the limited information described above only for the following purposes:

• To validate your active subscription (license validation)

• To process your purchase and provide you with a license key (via Lemon Squeezy)

• To respond to your support requests

• To send you important service-related communications (e.g., security notices, major version changes) – only if you have provided your email address

We do not use your information for:

• Marketing, advertising, or promotional emails (unless you have separately opted in, which we do not currently offer)

• Selling, renting, or trading to third parties

• Training AI or machine learning models of any kind

• Analytics, user profiling, or behaviour tracking

• Any purpose not explicitly listed above

Sharing your information

We share your information only in these limited circumstances:

Lemon Squeezy

• Payment processing, license validation, subscription management

• License key, installation ID, timestamp, email address (for purchase)

Legal authorities

• As required by law

Service providers (future)

• If we engage a third party to provide email or support services (we currently do not)

• Only as necessary, with contractual privacy protections

We do not share your information with any advertisers, data brokers, analytics providers, or other third parties for their own purposes.

Where your information is stored

• Your designs and files: Remain on your own computer. We never have access to them.

• License validation data: Processed and stored by Lemon Squeezy on their servers (likely in the EU or US). See Lemon Squeezy's privacy policy for details.

• Payment and transaction information: Stored by Lemon Squeezy. We do not store it.

• Support communications: Stored in our email system (we use a standard email provider) or CLickUp EU servers. If you are in the UK or EEA, note that email providers may store data on servers outside your jurisdiction when you send an email.

We do not operate our own servers for storing user data. All third-party processing is done under commercial agreements.

Data retention

• License validation logs: Lemon Squeezy retains validation records for as long as your subscription is active, plus up to 12 months for fraud prevention after account closure.

• Support emails: We retain support correspondence for as long as needed to resolve your issue, and typically delete it within 12 months after the last communication.

• Payment records: Lemon Squeezy maintains transaction records for accounting and legal compliance purposes (usually 6–7 years).

If you wish to have your email address removed from our support records sooner please contact us.

Your rights

Depending on your location (particularly if you are in the UK, European Economic Area, or certain US states), you may have rights under data protection laws including:

• The right to access the personal information we hold about you

• The right to rectification (correct inaccurate information)

• The right to erasure (request deletion of your information)

• The right to restrict or object to processing

• The right to data portability

• The right to withdraw consent (where we rely on consent – we do not currently rely on consent for any processing)

To exercise these rights, contact us. Since we hold minimal data about you (typically just your email address if you contacted support or purchased a license), we can respond quickly – usually within 30 days.

If you are not satisfied with our response, you have the right to lodge a complaint with the UK Information Commissioner's Office (ICO) or your local data protection authority.

Children's privacy

Filamental is not directed at children under the age of 13 (or the minimum legal age in your country to provide consent for data processing). We do not knowingly collect personal information from children. If we learn that we have inadvertently received information from a child, we will delete it promptly.

Changes to this Privacy Policy

We may update this policy from time to time to reflect changes in our practices or for legal reasons. The latest version will always be available on our website. If we make material changes, we will post a notice on our website and/or social channels.

The "Effective Date" at the top of this policy indicates when it was last revised.

Legal basis for processing (UK/EEA users)

Under UK and EU data protection law (UK GDPR / EU GDPR), we process your information on the following bases:

• Processing activity

Legal basis

• License validation (transmitting license key, installation ID, timestamp)

• Legitimate interests – to protect our software from unauthorised use and to ensure only paying subscribers have access

• Payment processing via Lemon Squeezy

• Contractual necessity – to fulfil your purchase and provide the Software

• Responding to support requests

• Legitimate interests – to assist our users and improve customer satisfaction

• Retaining records for legal compliance

• Legal obligation – e.g., tax laws, fraud prevention

We do not rely on consent for any processing because we collect so little data. Where we do seek consent (e.g., for optional marketing emails, which we do not currently send), you may withdraw consent at any time.
