Google API Services
When you connect your Google account, LANGR accesses Google Search Console performance data (queries, clicks, impressions, average position) and, optionally, Google Analytics 4 metrics — read-only — for the domains you own, in order to show rank-tracking, SEO insights and reports inside LANGR. We request only read-only scopes (webmasters.readonly, analytics.readonly); LANGR never modifies your Google data. You can revoke access at any time at myaccount.google.com/permissions.
LANGR's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Google user data is not used for advertising, is not sold or transferred to third parties, and is not used by humans except as required for security, to comply with applicable law, or with your consent.
