RecallDeck
Editorial policy
Who stands behind the material, what has been checked, and how to get an error corrected.
Publisher and accountability
RecallDeck is published and maintained by IP Alder, located in Astana, Kazakhstan. Contact support@recalldeck.dev about the materials or a correction.
RecallDeck sells access to its own study tools. When a resource roundup recommends RecallDeck, it recommends our own product. These roundups contain no paid or affiliate placements; their order is not a universal ranking.
What a reviewed label means
350 of the 1753 cards in this language currently have a published source review. 17 have a separate recall checklist. These counts do not mean the entire catalog has had an independent human review.
A review records its date, reviewer or review method, primary sources, scope and version limitations. Our process includes AI-assisted checks. An answer change invalidates its previous review until the new text is checked. An article’s update date alone does not certify every answer in it.
Sources and updates
Technical claims are checked against vendor documentation, specifications and other primary sources. Runnable examples are tested where the relevant toolchain is available. A documentation check or an unexecuted example is not described as a successful test run.
Language and library behavior depends on version. Historical explanations should be labeled accordingly. Corrections preserve the card’s identity and learner progress in both languages. A further-reading link is not evidence that every claim in an answer has been verified.
Request a correction
Use “Report a card error” below an answer, or email us. Include the card or article link, language, disputed claim and, where possible, a primary source or small reproducible example.
Corrections update the material while preserving study progress. A new review label covers only its recorded text and scope.
Use the material actively
Attempt an answer first, then compare its essential ideas and limitations. For coding problems, propose a solution and check edge cases. If you needed a hint for an important point, choose Again or Not answered.
The spaced schedule estimates when to review from your ratings. It does not measure interview readiness or guarantee a hiring outcome. Use the cards alongside practical work, projects and mock interviews.
