Domain Due Diligence
Report for Deepstash.com
Why we think so
Deepstash is a knowledge‑curation app and website (founded and registered in 2018) that claims “3M+” users and drives roughly 650k monthly visits (Aug 2025). The site uses modern infrastructure (Cloudflare CDN, HTTPS), standard analytics and payment providers (Google Analytics, Stripe), and has press coverage dating back to 2019–2023. However, multiple user reports on Apple/Play store threads and forum posts describe unexpected subscription renewals and denied refund requests, which have prompted several reviewers to call the service “scammy.” In short: technically legitimate and widely used, but exercise caution around subscriptions and refunds.
Risk Insights

Contradictory Signals
The service appears operational and widely used, but subscription and refund experiences are inconsistent for some users.
Signal A: High traffic, press coverage, and mainstream payment providers (low technical risk)
Signal B: Multiple user reports alleging 'scammy' subscription behavior (reputational risk)

Your Next Steps
-
1Before subscribing, note trial end dates and confirm renewal settings in the App Store or Google Play to avoid unexpected charges.
-
2If charged unexpectedly, attempt refunds through the platform (Apple/Google) first and keep timestamps/screenshots of trial/renewal notices.
-
3Contact Deepstash support and save all correspondence; escalate to your payment provider if refunds are refused and charges look unauthorized.
-
4Check the app’s store listing and recent reviews for fresh reports (search App Store / Google Play threads) to see if the subscription issue persists.
-
5Avoid giving payment details on third-party sites claiming Deepstash deals; use official app store or deepstash.com only.
