TL;DR: WA Spark is privacy-first. The Chrome extension runs 100% locally on your device. The web chat analyzer processes everything client-side. We collect zero personal data.
WA Spark's Chrome extension operates entirely within your browser. It does not transmit any data to external servers. All message processing, contact management, and analytics happen locally on your device.
The web-based chat analyzer at waspark.io/analyze processes your exported WhatsApp chat files entirely in the browser using client-side JavaScript. Your chat data never leaves your device and is discarded when you close the page.
We may collect anonymous, aggregated usage statistics (page views, referral sources) through privacy-respecting analytics. No personal information or IP addresses are stored.
Since we collect virtually no data, there is very little to use. Anonymous website analytics, if collected, are used solely to improve the website experience and understand which features are most popular.
All extension data (settings, templates, contact lists) is stored in your browser's local storage via the Chrome Extension Storage API. This data stays on your device and syncs only through your own Chrome profile if you have Chrome Sync enabled. We have no access to this data.
You are in full control of your data at all times. Uninstalling the WA Spark extension removes all locally stored data. Clearing your browser data has the same effect. No account creation is required to use the extension.
WA Spark is not directed at children under the age of 13. We do not knowingly collect any personal information from children. If you believe a child has provided us with personal information, please contact us and we will promptly delete it.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated “Last updated” date. Continued use of WA Spark after changes constitutes acceptance of the revised policy.
If you have any questions about this Privacy Policy, please reach out to us at support@waspark.io.
