About BlockSurvey
BlockSurvey is a web-based survey and form builder positioned around privacy. The site says responses are encrypted on the respondent's device with end-to-end encryption and a zero-knowledge model in which the survey owner holds the key, and that it uses no trackers, cookies or ads and can collect fully anonymous responses. AI features cover question writing, skip logic and multilingual support, plus analysis such as thematic analysis, sentiment analysis and response summaries. Surveys can be distributed by email, SMS, link, QR code or embed, with automatic follow-ups, and responses can be connected to third-party tools including Excel, Airtable, HubSpot, Power BI, Google Sheets, Zendesk, Slack and Discord. Pricing is not stated on the homepage. Claims of HIPAA compliance appear in customer testimonials rather than as stated product terms, and data passed to external integrations or processed for AI analysis leaves the platform's own encryption boundary as described.
