Scope
This Privacy Policy explains how LinkCheck collects, uses, stores, and shares information when you visit linkcheck.app, create or use a LinkCheck account at my.linkcheck.app, or connect optional third-party services such as Google Sign-In, Google Search Console, and Google Analytics 4.
Information we collect
We collect information you provide directly, such as your name, email address, account credentials, support messages, backlink-monitoring data, and other information you submit through LinkCheck. We also collect limited technical and usage information needed to operate, secure, troubleshoot, and improve the service, such as browser and device information, IP address, referring pages, and application activity.
Google Sign-In information
If you choose Continue with Google, Google may provide LinkCheck with your Google Account identifier, name, email address, email-verification status, and basic profile information. LinkCheck uses this information only to authenticate you, create or link your LinkCheck account, protect account access, and display basic account information. A verified matching email address may be used to link Google Sign-In to an existing LinkCheck account.
Google Sign-In is optional. You may continue to use LinkCheck’s supported non-Google account-access methods where available.
Google Search Console information
If you choose Connect Google Search Console, LinkCheck requests the read-only permission:
https://www.googleapis.com/auth/webmasters.readonly
This permission allows LinkCheck to read Search Console information for properties that your Google Account can access, including property identifiers, permission levels, and Search Console data used by the LinkCheck features shown to you.
LinkCheck uses this information to discover and display your available Search Console properties and provide the read-only Search Console functionality you request. LinkCheck does not request permission to add, edit, or delete your Search Console properties or data.
Optional Google Analytics connection
If you choose to connect Google Analytics, LinkCheck requests read-only access to the Google Analytics 4 accounts and properties available to the Google account you select. LinkCheck receives account and property identifiers and display names, web data-stream identifiers and default website addresses, and aggregate reporting metrics for properties you choose. LinkCheck stores up to 200 days of daily aggregate totals and Organic Search metrics, including sessions, engaged sessions, screen or page views, key events, and session key-event rate. It also caches the top five Organic Search landing-page paths for 7-, 28-, and 90-day views. Query strings and URL fragments are removed before a landing path is stored. LinkCheck uses this information only to match web streams to domains and display and refresh your domain intelligence.
LinkCheck requests the read-only OAuth scope https://www.googleapis.com/auth/analytics.readonly.
LinkCheck cannot create, edit, or delete Google Analytics accounts, properties, users, settings, audiences, events, or reports. LinkCheck does not request raw event export or user-level Analytics data. Access and refresh tokens are encrypted at rest and are used only to maintain the optional connection and run the read-only refreshes you authorize. LinkCheck’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
You can disconnect the shared Google data connection at any time. Disconnecting attempts to revoke the Google authorization, deletes the stored OAuth connection, and stops future Google Search Console and Google Analytics refreshes. Previously selected properties and cached aggregate reports remain until you remove the related data or delete your LinkCheck account, subject to the retention and legal obligations described in this policy. You may also remove LinkCheck from your Google Account’s third-party access settings.
How Google user data is used
LinkCheck uses information received from Google APIs only to provide and improve the user-facing authentication, Search Console, and Google Analytics features that you choose to use. LinkCheck does not sell Google user data, use it for advertising, transfer it to data brokers, use it to determine creditworthiness or for lending purposes, or use it to train generalized artificial-intelligence or machine-learning models.
Storage and security of Google data
LinkCheck stores the Google account association needed for sign-in. When you connect Google Search Console or Google Analytics, LinkCheck stores encrypted OAuth access and refresh tokens so it can maintain the shared Google data connection and perform the read-only operations you request. Selected property identifiers and the Google Analytics aggregate reports described above are also stored. LinkCheck applies reasonable technical and organizational safeguards designed to protect stored information. No internet transmission or storage system can be guaranteed to be completely secure.
Sharing and human access
LinkCheck may disclose information to service providers that process data on our behalf and are needed to host, secure, maintain, or support the service. We may also disclose information when required by law, to investigate abuse or a security incident, or as part of a merger, acquisition, or sale of assets with appropriate notice and protections.
LinkCheck personnel do not access Google user data except when necessary to provide support you request, investigate security or abuse, comply with law, or perform permitted internal operations using appropriately aggregated data. Service providers and personnel with access must handle the information consistently with this policy and applicable Google requirements.
Retention and deletion
Google account-link information is retained while the Google identity remains linked to your LinkCheck account. OAuth tokens and connection metadata are retained while the shared Google data connection is active. Disconnecting causes LinkCheck to attempt to revoke the Google authorization and removes the stored OAuth connection and tokens from the active LinkCheck database, stopping future Google Search Console and Google Analytics refreshes.
Information that you intentionally imported into or created in LinkCheck, including previously selected properties and cached aggregate reports, may remain in your LinkCheck account after disconnecting Google until you delete it, delete the related property or account, request deletion, or delete your LinkCheck account. Limited records may be retained when reasonably necessary for security, fraud prevention, legal compliance, dispute resolution, or enforcing agreements.
Your controls
You can disconnect the shared Google Search Console and Google Analytics data connection from LinkCheck account settings. You can also review or revoke LinkCheck’s access from your Google Account’s third-party connections page. Revoking access at Google prevents future API access but does not automatically delete information previously imported into or stored in your LinkCheck account.
To request access, correction, export, or deletion of your LinkCheck account or associated personal information, email admin@linkcheck.app. We may need to verify your identity before completing a request.
Other service providers
LinkCheck may use hosting, infrastructure, email-delivery, analytics, security, support, and payment providers to operate the service. These providers may process information only for the services they provide to LinkCheck and subject to their contractual and legal obligations. Payment providers process payment details under their own privacy terms; LinkCheck does not claim to store full payment-card details.
Policy changes
We may update this policy as LinkCheck’s features, providers, or legal requirements change. We will update the date above and provide additional notice when required.
