Last modified: 15 March 2023

By using the proton.me website and making use of a Proton Account (the “Account”) and all its related features, including Proton Mail, Proton Calendar, Proton Drive and Proton VPN (the “Services”), you agree to be bound by the following terms of service (the “Terms”). These Terms cover all present and future features provided by your Account. The Services are operated by Proton AG (“We”, the “Company”), a Swiss company located at Route de la Galaise 32, 1228 Plan-les-Ouates, Geneva, Switzerland.

If you agree to these Terms on behalf of a company or another legal entity, you represent that you have the authority to bind such entity, its affiliates, and all users who access the Services through your Account to these Terms. In the absence of such an authority, you are not authorized to use the Services.

Users of the Services

The Services are provided exclusively to individuals who are at least 13 years of age, or to minors who have obtained parental or legal guardian consent to open and maintain an Account.

The Services are provided exclusively to persons. Accounts registered by “bots” or automated methods are not authorized and will be terminated.

Each user is solely responsible for all actions performed through the Services.

Authorized use of the Services

You agree not to use the Services for any illegal or prohibited activities. Unauthorized activities include, but are not limited to:

  1. Disrupting the Company's networks and Servers in your use of the Services;
  2. Accessing/sharing/downloading/uploading illegal content, including but not limited to Child Sexual Abuse Material (CSAM) or content related to CSAM;
  3. Infringing upon or violating the intellectual property rights of the Company or a third party;
  4. Harassing, abusing, insulting, harming, defaming, slandering, disparaging, intimidating or discriminating someone based on gender, sexual orientation, religion, ethnicity, race, age, nationality or disability;
  5. Trading, selling or otherwise transferring the ownership of an Account to a third party (with the exception of Lifetime Accounts, which can be sold or traded exclusively through the Company);
  6. Promoting illegal activities or providing instructional information to other parties to commit illegal activities;
  7. Having multiple free Accounts (e.g. creating bulk signups, creating and/or operating a large number of free Accounts for a single organization or individual);
  8. Paying for your subscription with fraudulent payment means, such as a stolen credit card;
  9. Engaging in spam activities, which are defined as the practice of sending irrelevant or unsolicited messages or content over the internet, typically to a large number of recipients, notably for the purposes of advertising, phishing, or spreading malware or viruses.;
  10. Sending junk mail, bulk emails, or mailing list emails that contain persons that have not specifically agreed to be included on that list. You agree not to use the Services to store or share content that violates the law or the rights of a third party;
  11. Attempting to access, probe, or connect to computing devices without proper authorization (i.e. any form of unauthorized "hacking");
  12. Referring yourself or another one of your account to unduly benefit from our referral program's advantages.

Any Account found to be committing the listed unauthorized activities will be immediately suspended.

The Company may also terminate Accounts which are being used for illegal activities that are not listed in the present section, particularly in response to orders from the competent authorities informing of such illegal activity.

The Company reserves the right to suspend or delete free Accounts that have been inactive for a consecutive period of twelve months. For more information, we invite you to read our inactive account policy.

If you would like to contest the suspension of your account, please submit an appeal through our Abuse Appeal Form.

Limited warranties and liability

The Company does not make any warranty about the reliability of the Services or the security of user data, despite best efforts. The Service is provided “as is” and you agree not to hold the Company responsible nor to seek indemnification for any damages that may arise as a result of the loss of use, data, or profits connected to the performance of the Service or failure in such performance.

The Company has no obligation to store or forward the contents of terminated Accounts. We also have no obligation to store messages or contents for accounts that exceed their storage quotas.

Furthermore, you will not hold the Company liable or seek indemnification if confidential material is unintentionally released as the result of a security failure or vulnerability in the performance of the Services.

Due to the encrypted nature of the Services, you acknowledge that the Company has no ability or obligation to recover your data if you misplace your password.

Service level agreement (SLA)

For users with Proton for Business Accounts, the Company aims to provide Service availability of 99.95% or better. If downtime in any month exceeds 0.05% of that month, the Company will credit the user’s Account. Service credits are applied at the user’s request and will apply toward the balance due at the end of the next billing cycle (either monthly or yearly).

The Company calculates service credits in the following way:

  • If the monthly uptime is less than 99.95% but equal to or greater than 99.0%, the service credit is equal to 10% of the Service’s monthly cost;
  • If the monthly uptime is less than 99.0%, the service credit is equal to 30% of the Service’s cost.

Some performance issues are excluded from downtime calculations, such as:

  • Issues caused by factors outside of the Company’s reasonable control;
  • Issues that resulted from any actions or inaction by a user or a third party;
  • Issues that resulted from the user’s equipment and/or third-party equipment (not within the primary control of the Company). For the avoidance of any doubt, the Company does not provide any internet or network services and any performance issues related to that type of services shall be deemed not in the primary control of the Company;
  • Issues that arise from the Company’s suspension or termination of rights to use the Service in accordance with the Terms;
  • Downtime caused by reasonable scheduled maintenance that is announced in advance.


You agree that the Company, and any parents, subsidiaries, officers, employees, or third-party contractors cannot be held responsible for any third-party claim, demand, or damages, including reasonable attorneys’ fees, arising out of your use of the Services.


Our Privacy Policy and its sub-policies explain the way we handle and protect your personal data and privacy in relation to your Account, your use of the Services, and your browsing of the proton.me website. By agreeing to the present Terms and to be able to use the Services, you also agree to our Privacy Policy and its sub-policies.

If, in the provision of the Services, the Company processes, on the user’s behalf (where the user acts as a Data Controller), any personal data that is subject to the EU General Data Protection Regulation (GDPR), the company’s data processing agreement shall apply.

Intellectual property

All trademarks, service marks, logos, trade names, and other proprietary designations of PROTON (the “PROTON Trademarks”) displayed on this website are trademarks or registered trademarks of the Company, and numerous of the PROTON Trademarks are registered with the U.S. Patent and Trademark Office and with multiple trademark offices around the world. See, e.g., U.S. Reg. Nos. 4,751,245, 4,754,889; CH Reg. No. 662,183; EU Reg. No. 17,893,097. Nothing in these Terms and Conditions should be construed as granting, by implication, estoppel, or otherwise, any license or right to use any of the Proton Trademarks without our prior written permission in each instance. All goodwill generated from the use of the Proton Trademarks will inure to the Company’s exclusive benefit.

Terms of payment

Subscriptions for the Services are charged on a monthly, yearly or biyearly basis, depending on your selection. After the initial term, the subscription is renewed automatically for the same selected duration unless canceled by you. Credit balances are automatically deducted accordingly. You are responsible for keeping payment information in relation with your Account up to date.

You may cancel your subscription within 30 days of the initial purchase and receive a refund for any unused portion of the service period. Here, any unused portion of the service period refers to the prorated remaining full days of the subscription period. Refunds will be processed within 30 days of the request. To request a refund, please contact us using our support form. This refund option is only applicable to users who have subscribed to Proton's Services directly through Proton's official channels (website and apps). If you have subscribed to Proton's Services through the intermediary of a third-party, please refer to their respective refund policy.

Past the abovementioned 30-day period, the Services provided by the Company are generally non-refundable and any refund or credit given will be at the sole discretion of the Company. Paid Accounts which are terminated due to a violation of these Terms will incur the loss of all payments and credits and are not eligible for refund.

If the Company chooses to issue a refund for any reason, the Company will only refund in the original currency of payment. If you request a credit balance to be converted between different currencies which the Company supports, the Company has discretion over the exchange rate applied.

If you fail to fulfill your obligation of payment as a user of a paid Account, we may suspend your Account or delete it after an extended period of default.

If you rely on dispute or chargeback mechanisms of third-party payment processors, you waive your right to the above mentioned refund from the Company. Furthermore, if the result of the dispute or chargeback mechanisms causes the Company to be liable for an amount exceeding the price paid for the service (e.g. dispute fee), you authorize the Company to charge that amount on your account.

Modification to the terms of service

Within the limits of applicable law, the Company reserves the right to review and change these Terms at any time. As long as you are using the Services, you are responsible for regularly reviewing these Terms. Continued use of the Services after such changes are performed shall constitute your consent to them.

Applicable law and language

These Terms shall be governed in all respects by the substantive laws of Switzerland. Any controversy, claim, or dispute arising out of or relating to these Terms shall be subject to the jurisdiction of the competent courts of the Canton of Geneva. In case of discrepancy between the English version of these Terms and any translated version, the English version shall prevail.
