Overview
Lumo AI is Proton's entry in the privacy category tracked on this directory. The record holds one product line, Lumo Plus, priced at USD 9.99 per month as an entry-level plan. No country list is recorded for this provider, so anyone weighing up server or data locations will not find that answered here. What follows is drawn only from the specifications Proton has published for Lumo, read on 5 August 2026.
What the record shows
Proton states a free tier is available at $0.00, giving a way to try the assistant before paying. The company describes its ip sourcing as built on open-source components, with a no-logs approach stated by Proton; this is a claim made by the provider and is not something this directory has independently checked. Proton documents the network type as a privacy-focused AI assistant, which is a different kind of product to a proxy or VPN network, and buyers should read it as such. A 30-day money-back guarantee is stated under both the refund policy and payment methods fields on record; note that the specific payment methods accepted (cards, wallets, and so on) are not themselves documented, only the refund term attached to them. Support channels, uptime, and any independent audit of the no-logs claim are not documented at all.
Pricing
Lumo Plus is billed at USD 9.99 per month, an entry plan rather than a discounted annual rate, so the figure reflects a rolling monthly charge rather than a one-off cost. Against the set of 27 providers on this directory that also bill per month, Lumo Plus is cheaper than 31% of them, which places it in the higher-priced portion of that comparison rather than the lower one. No other product lines are recorded, so there is nothing here to compare it against internally.
Who it suits
On the record, Lumo suits someone who wants a privacy-oriented AI assistant from a known name in privacy software, and who is content to trial it free before committing to the $9.99 monthly plan. It does not suit anyone looking for a proxy or VPN network with defined countries or IP pools, since none of that is documented here. Buyers who need confirmation of specific payment options, data residency, or independent verification of the no-logs claim will not find that settled by this record alone.
Where to look closer
Ask Proton directly which payment methods are actually accepted, since only the refund term is on record rather than the payment types themselves. Ask which countries or regions the service operates from or serves, as none are listed here. Ask what support channels exist and what response times look like, since neither is documented. Finally, ask whether the no-logs approach has been subject to any independent audit, since as it stands this is a claim attributed to Proton rather than a verified fact.
