About Kleiren

Independent software.
A practical perspective.

Kleiren is an independent software and digital tools brand.

What we build

Software should make a task easier to complete. Our primary focus is useful business software and SaaS, while maintaining room for personal utilities and free tools.

How we work

Start with a clear problem. Define what a product actually does. Test it, explain its limitations and maintain its public availability. The portfolio contains working products rather than announcements for unfinished applications.

Our current portfolio

PNG View is available as a free, browser-local utility. New software is listed when its functionality and public release are verified.

Privacy choices

How optional measurement works

Optional measurement: with your consent, Across instrumented Kleiren pages, statistics count page views, successful calculations only on PNG View, and outbound clicks only for published approved affiliate offers. Counters are grouped by day and public page. Only a broad traffic-source category and a recognized public campaign label are sent. No filenames, file contents, form values, full referrers, URL queries, IP addresses or visitor identifiers are stored in these statistics. These are observations, not unique people or sales. Aggregate counters expire after 30 days. The HTTPS collector and hosting providers necessarily process connection information to deliver requests; their operational logs are separate from these statistics. Analytics and Awin affiliate attribution are separate choices, off by default. Affiliate attribution stays inactive until approved offer links are published. If selected for an available offer, it sends only the public article label to Awin on a deliberate outbound click; Awin and the merchant apply their own privacy terms and may use tracking cookies. Without affiliate consent, the same offer opens directly at the merchant. Your choice is kept only in memory for this page. Opening Privacy choices immediately withdraws both choices; you can then make a new selection. Ordinary access remains available without consent. Contact support@kleiren.com about privacy.

Optional measurement is off until you choose.
