We may also use personal information to localize content, remember preferences, comply with app marketplace rules, prepare support records, resolve disputes, perform analytics, monitor performance, manage consent choices, and generate aggregate business intelligence for service improvement.
5. Legal Bases
Where laws such as the GDPR, UK GDPR, Swiss data protection law, or similar frameworks apply, we rely on one or more legal bases including: performance of a contract or pre-contractual steps requested by the user; legitimate interests in operating, securing, marketing, and improving our services; compliance with legal obligations; and consent where required, including for certain cookies, certain analytics, certain advertising personalization, and certain device-level tracking activities.
Users may withdraw consent at any time where processing depends on consent. Withdrawal does not affect the lawfulness of processing before withdrawal.
6. Advertising, Analytics, and Monetization SDKs
Our mobile applications may include advertising, monetization, mediation, attribution, anti-fraud, measurement, and analytics services depending on app version, store requirements, market, and commercial strategy. These integrations may support splash ads, rewarded video ads, interstitial ads, banner ads, native ads, app open ads, mediation, performance analytics, revenue measurement, cohort analysis, fraud prevention, and conversion attribution.

These partners may collect or receive identifiers, device signals, approximate location inferred from IP, app interaction data, ad impression data, click data, consent signals, diagnostics, and anti-fraud information in accordance with their own privacy policies and the settings used in our app. In some jurisdictions, these partners may act as independent controllers, joint controllers, service providers, processors, or third parties depending on the function performed and the contract in place.
Where required by law or store policy, we implement consent prompts or privacy choice mechanisms before personalized advertising, cross-app tracking, or non-essential data access occurs. This may include compliance mechanisms for the IAB Transparency and Consent Framework, the IAB Global Privacy Platform, Google EU User Consent requirements, Apple App Tracking Transparency prompts, Google Play Data Safety declarations, and age-sensitive ad serving controls such as treatment for child-directed or teen-directed experiences where applicable.
We may configure ads to be contextual, non-personalized, limited, or disabled where required by law, platform rule, age gate, geographic scope, consent outcome, or internal policy. Users can generally reset device advertising identifiers, disable personalized ads at the device or account level, or use consent tools presented in-app where available.
7. App Marketplaces and Store Disclosures
Our apps may be listed on Google Play, the Apple App Store, Huawei AppGallery, Amazon Appstore, Samsung Galaxy Store, Xiaomi GetApps, Oppo App Market, Vivo App Store, and other lawful app marketplaces. Each marketplace may impose its own privacy, age, payment, security, content, tracking, and disclosure obligations. We design our notices to align with marketplace obligations, including but not limited to Google Play Families and Data Safety requirements, Apple App Privacy details, Apple ATT rules, user-generated content moderation requirements where applicable, refund and subscription framework rules where applicable, device permission disclosure requirements, and country-specific marketplace operator obligations.
App store operators may collect data independently when users browse, download, install, pay for, rate, review, or update our apps. Those activities are also governed by the applicable store operator's own legal terms and privacy notices. We do not control store operator processing outside the data they provide to us or data we receive through their APIs and reports.
8. Device Permissions
Depending on feature set, our apps may request permissions such as network access, storage access, camera, photo library, notifications, device identifiers permitted by the platform, or other permissions strictly related to product inquiry uploads, support attachments, media selection, notification delivery, login persistence, crash diagnosis, or advertising operations. Permission usage is limited to the feature described at the point of request, and users can manage permissions through their device settings subject to the functionality impact on the app.
10. Regional Privacy Rights
Depending on location, users may have rights to access, know, correct, delete, object, restrict, port, appeal, or withdraw consent regarding personal information. We also endeavor to respect regional requirements including, where applicable, the European Union General Data Protection Regulation, the UK GDPR and Data Protection Act, the Swiss Federal Act on Data Protection, the California Consumer Privacy Act as amended by the CPRA, Virginia VCDPA, Colorado CPA, Connecticut CTDPA, Utah UCPA, other United States state privacy laws as they become applicable, Canada's PIPEDA and provincial privacy laws, Brazil's LGPD, Australia's Privacy Act, New Zealand's Privacy Act, South Africa's POPIA, Singapore's PDPA, Japan's APPI, South Korea's PIPA, India's Digital Personal Data Protection framework, and other local laws that apply to our processing activities.
Where required by law, users may designate an authorized agent to make requests, appeal a denied request, or complain to a supervisory authority or data protection regulator. Verification steps may be required before a request is fulfilled. We do not discriminate against users for exercising privacy rights, except where different treatment is reasonably related to the value of data or legally permitted service differences.
Users in some jurisdictions may have the right to opt out of targeted advertising, profiling in furtherance of decisions that produce legal or similarly significant effects, or certain data sharing treated as sale or sharing under applicable law. We do not knowingly sell the personal information of children, and where law requires, we honor recognized browser-based or platform-level opt-out signals to the extent technically supported and legally required.
11. Age Limits and Children's Data
Our website and apps are intended for business users, professionals, project stakeholders, and adults or older teens permitted to use the services under local law and app store rules. They are not directed to children under the age required by applicable law. Depending on jurisdiction, this may include under 13, under 16, or another applicable threshold. If an app or feature is made available to users under a higher age threshold, localized age gates, parental controls, consent flows, or limited ad settings may apply.
If we learn that personal data has been collected from a child in violation of applicable law, we will take steps to delete the information, disable inappropriate tracking or ad personalization, and implement any additional corrective measures required by law or platform policy. Parents or guardians who believe a child has provided personal information may contact support@longqglass.com.
12. Security, Retention, and Complaints
We use reasonable administrative, technical, and organizational measures to protect data against unauthorized access, loss, misuse, alteration, or disclosure. These measures may include access limitation, credential control, transport security, logging, monitoring, and vendor due diligence. No system can be guaranteed to be perfectly secure, and users should exercise care when submitting business data or confidential materials.
We retain data for as long as necessary to provide the service, maintain business and legal records, resolve disputes, enforce agreements, support warranties and maintenance, manage tax and accounting obligations, investigate abuse, and comply with legal requirements. Retention periods differ based on the type of information, the country, the service channel, and the need to defend legal claims.
If you have a privacy complaint, concern, or request, contact us first so we can attempt to resolve it promptly. Where applicable, you may also complain to a competent data protection regulator, consumer authority, or marketplace operator if the concern relates to store compliance or advertising disclosures.
