Sterke encryptie, maar extreem risicovol herstelbeleid dat kan leiden tot totaal dataverlies.

Ik heb Proton meer dan 8 jaar gebruikt met een betaald Personal-abonnement.

Proton staat bekend om privacy en beveiliging, maar die beveiliging heeft een harde keerzijde.

Alle Proton-diensten (Mail, Drive, Pass en VPN) zijn gekoppeld aan één account met één hoofdwachtwoord. Verlies je dat wachtwoord, dan verlies je alles. In mijn geval betekende dat: e-mails, bestanden, foto’s, wachtwoorden en instellingen weg.

Proton adviseert een “security kit” met recovery codes. Heb je daar geen toegang meer toe, dan is de enige optie een reset — en die wist onherroepelijk alle data. Een recovery e-mailadres helpt niet om gegevens terug te halen. Alleen het oude wachtwoord of de originele recovery code kan data ontsleutelen.

Mijn probleem ontstond nadat ik op advies van Proton Pass een tweede wachtwoord activeerde. Daarna werd ik zonder waarschuwing uitgelogd uit alle apps en had ik nergens meer toegang toe. Een reset was de enige mogelijkheid, met volledig dataverlies tot gevolg.

De supportafdeling kon niets doen behalve handleidingen sturen of een reset aanbieden.

Daarnaast is Proton VPN op Ubuntu 24.04 extreem instabiel: veel crashes en sterke snelheidsdaling.

Ik ben inmiddels overgestapt op Mullvad VPN en een andere passwordmanager, die beide beter werken.

Conclusie: Proton biedt sterke encryptie, maar het herstelbeleid is meedogenloos. Ik wil niet langer afhankelijk zijn van één ecosysteem gekoppeld aan meerdere apps met één hoofdwachtwoord. Gebruik Proton alleen als je volledig begrijpt hoe het systeem werkt én meerdere offline back-ups van je recoverygegevens hebt.

Update. Twee mails gestuurd naar Proton support en de juridische afdeling om opheldering te vragen over het feit dat ik zonder waarschuwing vooraf werd uitgelogd uit alle sessies na het invoeren van het tweede paswoord in Pass. Week later geen response. Reminder gestuurd. De juridische afdeling voert wekelijks rechtszaken over klanten die hun data zijn kwijtgeraakt door onder anderen deze vreemde constructie. Bovendien heeft Proton drive een heel groot gebrek. Eenmaal alle fotos geupload naar Drive, met geen mogelijkheid kun je deze via een file constructie zoals gewone bestanden downloaden naar de eigen harde schijf of NAS omdaf ze niet zichtbaar zijn in de verkenner. Proton heeft dit erkend maar dit is al jaren bekend. Hierdoor 8 jaar aan fotos kwijtgeraakt. Zal Proton dit nooit vergeven. Hopelijk trekt Proton een keer het boetekleed aan.

Thanks for sharing your experience in such detail. Proton’s security model is built around zero access encryption, which means only the account password or recovery key can decrypt data. This is why, if both are lost, support can’t restore encrypted content. The security kit and recovery options are strongly recommended for this reason, and we know this model can feel unforgiving if something goes wrong.

Activating additional protections like a second password can change how sessions behave, but data access always depends on the original encryption keys. We agree this isn’t always intuitive, and clarity around these risks is important.

Regarding the VPN issues on Ubuntu, that’s not expected behavior. If you reported this, please share the ticket number so we can review it. If not, we recommend contacting support so the team can look into the instability you experienced.

We appreciate you taking the time to review our services.

Still waiting on refund after a week

I bought this product on subscription knowing that I could cancel within a month and get my first payment back. I cancelled it within 40 minutes and wrote to customer service. It’s a week later and have received only a vague and late reply which didn’t referr to a refund even though this was clearly stated in my email . Still waiting for the money. Steer clear.

Concerning your response, share my file number (4403411) how and to whom? I cannot reply to this thread, as you know I am sure.

Very well functioning service

I am very surprised to see so many negative reviews. I am sure there were genuine reasons for them. I have been using Proton Mail for over 6 years with paid subscription, including other Proton applications, never had a single issue to complain about. Very satisfied with all the functionality and services.

Not very impressive (yet?), but acceptable

I' ve been using Proton Mail for a few weeks now. Importing all history from my 2 Gmail accounts worked like a charm (some emails initially seemed to be missing, but that was just because Proton groups emails into conversations differently from Gmail). It has to be noted that all your email addresses appear into a unified inbox, there's no easy way to split them - which may be fine or not according to your personal preferences.

Features are definitely not as good as in Gmail - one striking example is how tedious it is to search the body of emails (and it seems it can't be done at all in the mobile app?!). There are some annoying bugs and some UX choices are questionable. Customer support is willing to help, but you have to insist and it takes several exchanges of messages before they actually start working on your problem.

The Proton Authenticator app is really good, better than Google's IMO, and exporting + importing accounts into it was a breeze.

Overall, despite its many flaws, I think I'll stick with Proton for the commitment to privacy and the European storage locations (I wouldn't feel comfortable relying on the US these days). The fact that the Proton company is owned by a foundation and that they open up their source code makes me trust their ethics - that's for sure better than just having "Don't be evil" as a motto.

Emails aren't reliable, customer service is horrendous and deceptive

In October 2025, after a third instance of my Proton email service not consistently sending or receiving emails, I asked ProtonMail to cancel my account and send me a refund.

I was assigned Maja, who offered “2 extra months in the form of credits” if I gave them a “chance to resolve” the issue. I explained that reliability was more important than anything else, and that I wanted to end my ties to ProtonMail as quickly as possible.

A new customer support agent, Ana-Marija, responded and stated that she would “proceed with the downgrade.” However, what she concealed was that the “downgrade” was not a refund, but months of “credits” – something I had already declined.

Three weeks later, I noticed I never received my refund, so I contacted Ana-Marija and asked for assistance in finishing my request. What followed was infuriating back-and-forth email exchanges which defied European Commission standards (which they are affiliated) as well as US Consumer Laws (where I am located).

ProtonMail customer representatives would ask me to provide proof of one thing or another under the auspices that, if I did so, they would “reconsider the refund” for me. So, each and every time, I would spend the energy and resources to dig up the information and proof they requested, only for them to not “reconsider the refund” as they promised.

After enough back-and-forth, my case was assigned a third customer service rep, Supervisor “Marija” (who is not the same person as Ana-Marija). Rather than reading the earlier email exchanges I had had with Ana-Marija, Marija had me re-explain the circumstances of the case.

At Marija’s request, I re-explained my customer service ticket concerns, but explained that I was not interested in troubleshooting the issue, especially if a refund was not actually available. I engaged with Marija as a good-faith effort, but expressed that I believed the situation was at a point where it was inappropriate for us to continue dialogue without a third-party representative mediating the exchange, as it felt like they were intentionally disregarding the information I was sending at their request.

Despite my request for communication to stop, ProtonMail continued engaging with me, specifically with a new customer service rep named Ivan who reached out to me after I believed the conversation had finished. Ivan contradicted each of the customer service reps I’d already dealt with, and talked to me as if I was the one who contacted him to continue pursuing a refund. I responded by explicitly explaining that I felt like the communication had risen to the level of harassment.

To summarize:

- Despite Proton’s terms of service explicitly referring to the possibility of a refund “at the discretion” of the company, customer service reps would deny the possibility of a refund. After I acknowledged this, they (Maja, then Ana-Marija, then supervisor Marija, and finally Ivan) would but then bring up that they had the authority to offer a refund if I troubleshot with them. I would do so in good faith, only to find that they had no intention to offer this refund, and after providing the info they requested, they would revert back to stating they could not violate “Proton’s refund policy.” As such, they received free IT troubleshooting by deceiving me into engaging with them and by having me track down the information they needed. I am not happy that a “discretionary refund” was being wielded as a carrot in front of me when there was ultimately no intention of ever granting me the refund. I worked for free for Proton’s customer support agents.

- When it became clear that ProtonMail had no intent to grant the refund, I requested no more contact from them without being afforded a third-party present. Despite this, Proton continued emailing me on multiple occasions (specifically Marija and Ivan).

- I requested a chargeback from my credit card and filed a BBB report, where they already have an outstanding "F" rating there.

FEB 5 UPDATE - MY RESPONSE
Hi, no thanks.
First of all, it is unsafe to put ticket numbers across the Internet.
Secondly, did you read my complaint? I don't know how many times or how many different ways I need to say this: I do not want to talk to you without a neutral third party intermediary present, and it is inappropriate for you to keep pushing to speak with me.
I currently have an open case against you with the BBB; please respond to their inquiries, which you have not done yet. I will not be speaking to you "privately" anymore.

I just received an email from Proton: "We're donating $1.27 million"... Start by restoring (or refunding) the customers who lost their subscriptions by trying to delete your email address... and without any technical know-how worthy of an IT professional.

Wenn man keine Probleme hat ganz OK

Wenn man keine Probleme hat, funktioniert alles gut. Hatte keine gravierenden Verbindungsprobleme usw.
Doch nun zu mein Problem;
Ich hatte mir zu testzwecke eine Email erstellt. Dies klappte auch Problemlos. Da mir die Email Adresse nicht zusagte wollte ich diese löschen und mir eine andere erstellen. Also legte ich los und löschte die zuvor erstellte Email. Während des ganzen lösch Vorgang stand dort die Email Adresse die ich zu Testzwecke erstellt hatte. Doch als die Löschung durch war, stellte ich fest, das ich versehentlich den kompletten Proton Account gelöscht hatte.
Premium Support funktioniert nicht, den der geht nur aus dem Proton Account.
Nach gut zwei Tagen hat sich endlich der Support gemeldet und stellt die Fragen die ich schon beantwortet hatte. Jede Bearbeitung dauert min. einen Tag. Dies zieht sich nun schon über eine Woche her und im Grunde genommen bin ich bis heute nicht weiter. Hab weder das restliche Geld zurück bekommen noch meinen Proton Account.

Wie ich hier aus den Bewertungen Erfahren hab, haben einige dieses Problem. Email gelöscht und so ganzen Proton Account gelöscht. Hier sollte unbedingt nachgebessert werden, wenn diese Praxis nicht zum Geschäftsmodell gehört!

Da ich Anfangs nichts vom Support hörte, hatte ich den Support nochmals angeschrieben.

As a sole email user

As a sole email user, I find the current and past plans inflexible. My limited use of email and lack of interest in other products or a second account for a family member puts me at a disadvantage. I’m forced to purchase unnecessary features and products to access the writing tools (Mail Assistance) I’d like. This inflexibility makes me hesitant to continue using Protonmail. While I’ve never been unhappy with the service, paying for something I don’t use and need is unacceptable. Using my latest MacBook, I’ve found workarounds for AI proofreading, but the question remains: why pay for a higher plan if I don’t need more than half the features?

Ik zou er niet aan beginnen!!

My ticket case is Your request (4399984)
And I want my money back. I canceled 1 febr. So only a few days I used Proton. BUT I WANT MY MONEY!!! That's all.

Hmmm veel werkt niet optimaal. Delen van je agenda , bv. met familie in Google Calender, gaat heel traag en de terugkerende afspraken worden helemaal niet gedeeld. De vervanging van Office oogt wel heel 'goedkoop' en dat is het pakket eerlijk gezegd niet. Bedrijf reageert ook bedroevend slecht op vragen. Bij een vraag kreeg ik herhaaldelijk de vraag min of meer terug, terwijl de vraag gewoon echt duidelijk was. Ze reageren helemaal slecht op berichten. Zit nu te wachten tot mijn opzegging is verwerkt EN ik mijn geld terug krijg. Binnen 30 dagen nl. opgezegd.

Not perfect but always reliable and transparent

I've been a user of Proton's suite of products for a few years now, I first created my account about four years ago. While Proton isn't perfect and some of their products could use quite a bit of work (looking at you, Drive), it has always been reliable and Proton is transparent when it comes to issues.

Just today, I decided to upgrade to Visionary while it was still an option, and even though it was quite a high price, what I got was certainly worth it.

The dumbest email service in the world

In any case, i don't like put only one star but ..

Protonmail is the dumbest email service in the world

If two people access their email from the same IP address, both email address are automatically blocked and unusable.

You might say that's impossible, but yes, they're that stupid.

Not creating multiple email addresses from the same IP address would have been a good idea, but not allowing two different people to connect via the same IP address? You have to be seriously delusional, and profoundly so, if I may add.

How can such nonsensical behavior be used in a business ?

Some people at ProtonMail should be fired.

Kom trygt!

Jeg skiftede fra Outlook/hotmail til Proton for ca. ½ år siden og har kun været tilfreds. Fungerer perfekt for mig. Jeg er også vild med, at tråden i en korrespondance kun ligger på en enkelt mail og ikke som i Outlook spredt på samtlige aktioner i tråden.
Eneste host er, at da jeg skulle overføre mine mapper fra Outlook, var de tomme, da jeg åbnede dem på Proton. Det havde jeg ikke lige ventet......

Erpressung statt Service | Kontosperrung & Rückerstattungsverweigerung

Ich habe eine Jahreslizenz „VPN Plus“ bei Proton bezahlt. Nach zwei Monaten funktionierte der Dienst plötzlich nicht mehr – aus technischen Gründen, die ich nicht verschuldet habe.

Der Support war intransparent, hinhaltend und ignorierte meine Anliegen. Als ich auf Rückerstattung bestand, wurde ich unbegründet als Betrüger bezeichnet, meine Zahlungsmethode entfernt – und mein Konto ohne Vorankündigung gesperrt.

Als ich bei PayPal einen Fall eröffnete, kam die Antwort: „Schließe den Fall, dann bekommst du dein Konto zurück.“ Das ist Erpressung.

Ich habe Proton mehrfach aufgefordert, mir anteilig das Geld zurückzuzahlen – erfolglos. Inzwischen habe ich die Sache bei der Verbraucherzentrale Hamburg und der Stiftung für Konsumentenschutz in der Schweiz gemeldet.

Proton nutzt seine Marktposition aus, sperrt Nutzer willkürlich und verweigert Service. Finger weg – das Image steht im kontrastreichen Gegensatz zur Realität.

Update: Antwort auf Protons Reaktion

Proton in "":
"Wenn eine Rückbuchung oder ein Zahlungsstreitfall eröffnet wird, können Konten gemäß unserer Zahlungs- und Rückbuchungsrichtlinie vorübergehend gesperrt werden, während der Fall vom Zahlungsanbieter bearbeitet wird. Dies ist ein Standardverfahren und dient nicht als Druckmittel, sondern soll doppelte Lösungen verhindern, solange ein externer Streitfall aktiv ist."

Interessant. Fragt man sich, was mit doppelte Lösungen gemeint sein soll, wo die Rechtslage hier eindeutig ist. Ferner zu sagen, es diene nicht als Druckmittel, ist angesichts der Situation eine recht kühne Aussage.

Proton denkt offenbar, dass man sich kognitiv im Spätherbst befinden muss. Anders kann ich mir nicht erörtern, wie sie ihr fragwürdiges Geschäftsgebaren rechtfertigen.

Update 08.02.2026:

PayPal hat zu meinem Gunsten entschieden und ich habe nun den kompletten Betrag zurück erstattet bekommen.

Hätte ich den Fall auf Wunsch von Proton geschlossen, ich hätte vermutlich weder Geld, noch Konto je wieder gesehen. Zumindest lassen das Geschäftsgebaren Protons und nicht zuletzt auch andere Bewertungen hier darauf schließen.

Es lohnt sich also, auf die eigenen Instinkte zu hören und sich in Geduld zu üben.

When a chargeback or payment dispute is opened, accounts can be temporarily restricted under our payment and chargeback policy while the case is handled by the payment provider.

Not always the cheapest option for the services they provide, and some things definitely need to improve.

But negativity aside, I've never had any issues with their customer service. They have been super helpful and friendly. And in a world where more and more personal information is available for anyone to see without your consent, the privacy first aproach of Proton is top-notch and a welcome change.
Yes there isn't the integration like with Google but I know my data stays my data.

Slick, modern interface

Recently made the switch to Proton Mail and Drive (partly to decouple from US-based Gmail and Outlook). So far so good. The system feels slick, fast, easy to manage. The free tier is very limited so upgraded so I can also use our family domain name. The apps are reasonable on iPhone (iPad less so). The only caveat on MacOS is you need to use the "Proton Bridge" app if you want to continue using Mail (or other email app) to work with the encryption. The Drive app works very well though. Only downside was a massive lack of e-mail and username availability, probably too late to the party. A few more domain extensions would help!
