Rights, credits and corrections

Updated October 24, 2026. AltStack at altstack.space is operated personally by Sushil Kumar Sah in Nepal. Contact ssah74475@gmail.com or use the contact form.

AltStack’s identity and content

Sushil Kumar Sah operates this directory at altstack.space. Copyright is asserted only in original material to the extent owned and protected by applicable law. It does not claim ownership of listed products, their names or artwork, general facts, software ideas or third-party licensed code. A website notice does not establish that the AltStack name is a registered trademark. No patent or trademark registration number is represented here.

Independent product identification

Product names, logos and interface images identify the relevant tools and belong to their respective rights holders. A listing, comparison, logo or outbound link does not imply sponsorship, affiliation or endorsement. Software licenses do not automatically license a project’s trademark or all embedded artwork. Follow each asset-specific grant and notice.

Report a rights concern

Email ssah74475@gmail.com with the affected AltStack URL, identification of the work or mark, the ownership or authorization basis, the specific concern and a contact address. Do not include government identity numbers in an initial report. The operator can review, correct, replace or restrict the disputed material where appropriate. This channel is a direct rights-review contact; it does not claim registration as a statutory notice agent or guarantee a legal outcome. A general disclaimer cannot cure unauthorized reuse.

Documented artwork credits

The entries below link the recorded author, source, grant and notice for reviewed artwork. They are not a certification that every legacy asset has completed rights review. Original files are retained; some display thumbnails are resized or re-encoded for delivery. Historical previews are labelled on their tool pages. The applicable grant governs reuse, including attribution and share-alike conditions where relevant.
