Privacy Policy

To understand usage and improve reliability, wordDNA sends limited first-party analytics by default:

• a random, resettable installation identifier and per-launch session identifier;
• first launch, app opens, session duration, screens and feature interactions;
• query counts, query-length ranges, whether a result was found, match type, and response-time ranges;
• paywall interactions and aggregate study or review actions when those events are available;
• app/build version, iOS version, device family, app language, locale region, and country-level region.

“First launch” is our near-real-time new-install signal; it is not an exact App Store download count.

Our first-party app analytics service does not accept or store search words, definitions, examples, favorites, custom word-pack content, Apple ID, name, email, phone number, precise location, contacts, advertising identifiers, or clipboard content.

The server may use the network address momentarily to apply abuse limits and infer a country code. The full address is not written to the wordDNA analytics database, and access logging is disabled for wordDNA analytics routes.

The free version of wordDNA may display a Google AdMob banner at the bottom of a word-entry detail screen. Subscribers with ad-free access do not receive these in-app ad requests. We do not send your dictionary search words, definitions, saved words, or learning records to Google for ad targeting.

When an ad is requested, the Google Mobile Ads SDK may process information such as your IP address and approximate location derived from it, device and app information, device or advertising identifiers when available and permitted, ads shown and interactions with them, diagnostics, crash information, and performance data. Google may use this information to provide and measure ads, limit repeated ads, prevent fraud and abuse, maintain its services, and personalize ads where permitted by your consent and settings.

Where required, wordDNA uses Google's User Messaging Platform to ask for and store your advertising consent choices before requesting ads. When Google requires an ongoing privacy-choice entry for your region, open Profile → About → Ad Privacy Options to review or change those choices. You can also manage advertising permissions in iOS Settings and manage Google ad personalization in your Google account.

Learn more in Google's explanation of how it uses information from apps that use its services and its Privacy Policy.

In wordDNA, open Profile → Privacy & Data to turn off basic analytics at any time. Turning it off deletes pending analytics stored on the device and stops future collection.

Choose Reset & Delete Analytics ID to request deletion of server records linked to the current random identifier and create a new identifier that cannot be linked to the old one. You can also contact us for privacy questions or requests.

wordDNA analytics are sent over HTTPS to infrastructure we operate on Tencent Cloud. Raw app events are retained for up to 90 days. An installation summary is removed after approximately 13 months of inactivity. A bounded offline queue may remain on the device for up to 7 days and never exceeds 2 MB.

We use our first-party analytics information only for analytics, security, reliability, and product improvement. We do not sell it, provide it to Google for ad targeting, combine it with third-party data for tracking, or share it with data brokers. Google's separate processing of advertising data is described in the Google AdMob section above.

The website uses separate first-party service analytics and anti-abuse controls. These may record page views, submitted website search terms, opened entries, scroll depth, browser language, device category, referring site, User-Agent, and automated-client indicators. Network addresses and proxy-chain addresses are converted to salted hashes before analytics storage; they are not used for advertising or cross-site tracking.

The website may use an HTTP-only cookie to limit automated scraping and keep the service available. Website search terms are not part of wordDNA app analytics.

We limit analytics fields, validate incoming events, rate-limit the public endpoint, restrict database access, and use HTTPS in transit. No system can guarantee absolute security. Depending on where you use the service, information may be processed outside your country or region.

Our services are not designed to collect personal information from children. If you believe a child has provided personal information, contact us so we can investigate and delete it.

We may update this policy when features or legal requirements change. The effective date above will change, and material changes will be communicated in the app or on this page when appropriate.
