Privacy Policy

Last updated: November 11, 2025

Thank you for choosing Signalgrid (“we”, “us”, “our”). Protecting your privacy and the personal data you entrust to us is a core priority. This Privacy Policy explains what information we collect, how we use it, the measures we take to protect it, and the rights you have in relation to your personal data.

1. Responsible Entity

For purposes of applicable data protection laws, the responsible organization is:

Signalgrid e.U.
Janis-Joplin-Promenade 22/106
1220 Vienna, Austria
Email: privacy@signalgrid.com

2. Scope of this Policy

This Privacy Policy applies to all users of the Signalgrid service (the “Service”), including website usage, account registration, and interaction with our push-notification platform. It explains how we process personal data both through the Service itself and through associated online interfaces.

3. Data We Collect and the Purpose of Processing

We limit our collection and processing of personal data to that which is necessary to deliver and maintain the Service, to provide a secure and reliable platform, and to comply with our legal obligations. Specifically:

• Account Information: When you register with our Service, we collect your email address, password (stored in hashed form), and a chosen display name or username.
• Service Usage Data: We log technical and usage-specific data, including but not limited to timestamps of access, device identifiers, message counts, API usage metrics and connectivity information, insofar as necessary to support performance, reliability, troubleshooting and abuse prevention.
• Security and Audit Data: To protect the Service and its users, we process log files, IP addresses, error reports, and related metadata for fraud detection, security incident response and system diagnostics.

These processing activities serve the following purposes:

• Provision, operation, maintenance and improvement of the Service.
• Ensuring authentication of users, integrity of messages, and prevention of unauthorized access.
• Detecting, preventing and mitigating misuse, fraud or security breaches.
• Compliance with legal or regulatory obligations to which we are subject.

4. No Social Media Plugins or Analytics Tracking

We do not incorporate social media sharing buttons or embedded social-network plugins on our site, and we do not deploy Google Analytics, Facebook Pixel or comparable third-party behavioural tracking technologies. Consequently, no user-tracking or profiling for marketing purposes is performed by us or shared with advertising networks.

5. Data Sharing and Third–Party Disclosure

We do not sell, rent, lease or otherwise trade your personal data with third parties. Your data may only be disclosed in the following circumstances:

• Where you have given your explicit consent for a particular disclosure;
• Where we are required to do so by a valid court order, statute or regulation;
• Where disclosure is necessary to enforce our Terms of Service, to defend our legal rights, or to protect the rights, safety or property of others or us.

6. Data Retention and De-Identification

We retain personal data only for as long as is necessary to fulfil the purposes outlined in this Privacy Policy or as required by legally mandated retention periods. Once data is no longer required, we will securely delete it or render it irreversibly anonymised.

7. International Data Transfers

Data processed by us may be stored or transmitted to servers located in jurisdictions outside your country of residence. Where data is transferred internationally, we implement and rely upon appropriate safeguards (such as standard contractual clauses or other legally accepted mechanisms) to ensure an adequate level of protection for your personal data.

8. Data Security Measures

We apply technical and organisational safeguards designed to ensure a level of security appropriate to the risks posed by the processing. These measures include, but are not limited to:

• Encryption of data in transit (TLS/SSL) and, where appropriate, encryption at rest.
• Access controls limiting access to authorised personnel based on role.
• Firewalls, intrusion detection systems, and regular security assessments.
• Incident response procedures to address potential data breaches.

9. Your Rights and How to Exercise Them

Under applicable privacy legislation (including the EU General Data Protection Regulation (“GDPR”) and similar laws elsewhere), you have the following rights in relation to your personal data:

• Right of access: You may request a copy of the personal data we hold about you.
• Right of rectification: You may ask us to correct inaccurate or incomplete data.
• Right of erasure (“right to be forgotten”): You may request that we delete your personal data subject to legal or contractual exceptions.
• Right to restriction of processing: You may ask us to limit the processing of your data under certain circumstances.
• Right of data portability: To the extent technically feasible, you may request your data in a structured, machine-readable format and transfer it to another controller.
• Right to object: You may object to processing based on our legitimate interests in certain cases.
• Right to withdraw consent: To the extent processing is based on your consent, you may withdraw that consent at any time without affecting the lawfulness of processing prior to withdrawal.

To exercise any of these rights, please contact us at privacy@signalgrid.com. We will respond to your request in accordance with applicable legal timeframes and may require identity verification to protect your data.

10. Children and Underage Users

The Service is not directed to children under the age of twelve (12). We do not knowingly collect personal data from minors under sixteen without appropriate parental or guardian consent. If we become aware that such data has been collected without verification of consent, we will promptly take steps to delete it.

11. Changes to this Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, legal requirements or the functionality of the Service. When we do, we will revise the “Last updated” date at the top of this policy and make the new version available via our website. We will notify users of material changes via the Service or email if required by law.
