Privacy Policy

Last updated June 28, 2026

Scope

This Privacy Policy explains how Quassum MB ("Quassum", "we", "us", "our") handles personal data collected through:

www.quassum.com
direct emails, contact requests, and business conversations with us
client, supplier, and partner relationship management

This Policy is a root company privacy policy. It does not try to fully describe every Quassum product, app, beta, standalone domain, app store listing, or third-party platform integration.

If a specific product or service has its own privacy policy, in-product notice, app store disclosure, or other product-specific privacy terms, that product-specific document supplements this Policy and controls for that product to the extent of any conflict.

You are responsible for reviewing the privacy documents linked for the specific product or service you choose to use. If you use a product without reviewing its applicable privacy documents, those documents may still apply to your use to the maximum extent permitted by law.

Data Controller

The data controller for this Policy is:

Quassum MB
Algirdo 18-11
LT-03218, Vilnius
Lithuania

Product-Specific Privacy Documents

If you use one of the products below, review its product-specific privacy document as well:

Some Quassum products may also publish separate privacy terms on their own domain, inside the product, or through the relevant app marketplace.

Personal Data We Collect

Depending on how you interact with us, we may collect:

Information you provide directly

name
email address
company name
job title
the contents of your message, request, or project brief

Information collected automatically

When you use the main Quassum website, we or our service providers may collect technical and usage data such as:

IP address or derived approximate location
browser, device, and operating system details
referring pages, landing pages, and page views
timestamps, session activity, and interaction events
security, anti-abuse, and server log information
cookie, local storage, or similar technical identifiers where used

Information from third parties

We may receive data from:

analytics and hosting providers

app stores, distribution platforms, or other marketplaces
referral partners or public business sources

Why We Use Personal Data

We may use personal data to:

operate, secure, maintain, and improve our website
respond to inquiries and communicate with you
assess project fit, prepare proposals, and provide services
manage contracts, invoices, records, and compliance obligations
measure website performance and understand audience interest
prevent fraud, abuse, unauthorized use, or legal violations

Legal Bases

Where the GDPR or similar laws apply, we usually rely on one or more of these legal bases:

Contract: to take steps at your request or perform an agreement with you
Legitimate interests: to run, secure, improve, and market our business in a proportionate way
Legal obligation: to comply with tax, accounting, regulatory, or law-enforcement requirements
Consent: where law requires consent for specific processing activities

Cookies and Similar Technologies

The main Quassum website may use cookies, local storage, scripts, and similar technologies for security, functionality, measurement, and performance.

You can usually control cookies through your browser settings. Blocking certain technologies may affect how the website works.

Where applicable law requires consent for non-essential technologies, our intended basis is your consent.

Analytics and Third-Party Providers

We use third-party or self-hosted service providers to support our business. Depending on the product, page, or workflow involved, these may include providers for:

website hosting and delivery
privacy-oriented analytics
email and communications
payments, bookkeeping, or invoicing
app distribution platforms and marketplaces
legal, compliance, and professional advisory support

These providers may process personal data on our behalf or, in some cases, act as independent controllers under their own privacy terms.

International Transfers

Some of our service providers may process personal data outside Lithuania or the European Economic Area. When that happens, we aim to rely on an appropriate legal transfer mechanism, such as adequacy decisions or standard contractual clauses, where required.

Data Retention

We keep personal data only for as long as reasonably necessary for the purposes described above, including to meet legal, accounting, reporting, and dispute-resolution requirements.

In practice:

inquiry and correspondence records are usually kept for as long as needed to handle the request and reasonable follow-up
client and supplier records may be kept for the duration of the relationship and any legally required retention period afterward
technical logs and analytics data are kept for the period reasonably needed for security, diagnostics, and reporting

Your Rights

Depending on the laws that apply to you, you may have rights to:

request access to your personal data
request correction of inaccurate data
request deletion of your data
request restriction of processing
object to certain processing
request data portability
withdraw consent where processing depends on consent
lodge a complaint with your local supervisory authority

If you want to exercise any of these rights, contact us at [email protected].

Children

The main Quassum website is not directed to children, and we do not knowingly collect personal data from children through the main website.

Third-Party Sites and Products

Our website may link to third-party websites, app stores, external product domains, and client systems. Their privacy practices are governed by their own documents, not this Policy.

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will post the updated version here and revise the "Last updated" date.
