What's New in Psylo

1.3.1

August 4, 2026

Psylo 1.3.1 focuses on strengthening privacy protections and improving reliability. Privacy • Fixed a potential IP leak through the WebTransport and WebAuthn (Passkeys) JavaScript APIs. These APIs are now disabled by default for all silos and can be re-enabled individually from the Advanced section of each silo. • Fixed a potential DNS leak caused by DNS prefetching via HTML link tags. DNS prefetching is now completely disabled. Improvements • Fixed an issue that could cause content filtering and ad blocking to work unreliably for some users. • Added an option to manually re-download content filters if one or more filters fail to download. • Updated the TLS certificates used for Psylo Server certificate pinning. • Minor wording improvements on the subscription screen.

Serious Compatibility Issue After Psylo 1.3.1 Update

Hi Psylo Team,

I’d like to report a serious compatibility issue I’ve experienced since updating from Psylo 1.3.0 to 1.3.1.

With version 1.3.0, I had very good compatibility with certain websites. However, immediately after updating to 1.3.1, I started experiencing significantly more account restrictions on some websites under otherwise similar usage conditions.

I noticed that 1.3.1 introduced several privacy-related changes, including disabling WebTransport and WebAuthn by default, as well as completely disabling DNS Prefetch.

I understand the privacy and IP-leak concerns behind these changes. However, I’m concerned that completely removing certain normal WebKit/Safari behaviors can make a Psylo environment behave noticeably differently from a regular Safari environment.

WebTransport and WebAuthn can at least be re-enabled through the Advanced settings. DNS Prefetch, however, appears to have been completely disabled without an option for the user to restore the previous behavior.

Would it be possible to add a per-Silo option such as:

Disable DNS Prefetch

so users can choose whether DNS Prefetch should be enabled or disabled, just like WebTransport and WebAuthn?

For users who prioritize maximum privacy protection, it could remain disabled by default. But users who need maximum website compatibility could choose to enable it and accept the associated privacy trade-off.

In my case, the difference between 1.3.0 and 1.3.1 has been substantial enough that I would strongly prefer the ability to reproduce the networking behavior of 1.3.0 as closely as possible.

I’m not claiming that DNS Prefetch alone is responsible for the account restrictions I’ve observed. However, because the issue appeared immediately after upgrading from 1.3.0 to 1.3.1, I believe having the ability to individually control these new restrictions would be extremely useful for compatibility testing and troubleshooting.

Additionally, would it be possible for the Psylo team to provide an official way for affected users to temporarily install or downgrade to version 1.3.0?

For example, if possible, you could provide a previous 1.3.0 build through TestFlight or another official installation method. This would allow us to directly compare 1.3.0 and 1.3.1 under the same conditions and determine whether the compatibility issue is specifically related to the changes introduced in 1.3.1.

Even if providing an older build is only temporary and intended for troubleshooting purposes, it would be extremely helpful.

Please consider adding a DNS Prefetch toggle in a future update and, if possible, providing access to the previous 1.3.0 build for compatibility testing.

Expensive. Unethical developers.

I initially wrote a review giving it 3 stars because, despite the expensive price and annoying yellow block saying your subscription expired, you could still use the basic offline features (which don’t cost the devs any money) with your own proxy or none at all.

Days later they updated the app and completely blocked all basic features unless you pay $11/mo. There was no mention of this in the changelog. They basically tricked people into updating and took away 100% of the previously free features.

I’ll be deleting all of my comments on social media recommending this app for privacy, and I’ll mention that the developers are unethical and untrustworthy any time I see the app mentioned.

Response from developer

Hello. We’ve always been clear that Psylo requires a paid subscription. We’ve never advertised or offered a free tier, although it’s something we’re still considering for the future. The ability to continue using custom proxies after a subscription expired was a bug, not an intentional free-tier. That’s why Psylo displayed the yellow subscription expiry banner. This bug was fixed in version 1.3.0 along with many other issues and improvements. We don’t try to mislead or trick our users, so we don’t think it’s fair to characterize our actions as unethical. If you have concerns or questions about how Psylo works, we’re always happy to discuss them in good faith. Original reply: Hello! Thanks for downloading Psylo. We understand subscription pricing is an issue for many and we're discussing alternatives to offer Psylo at a cheaper price, though we still haven't settled on what that could look like.
