Python Package Index (PyPI) Terms of Service

Thank you for using PyPI! Please read this Terms of Service agreement carefully before accessing or using PyPI. Because it is such an important contract between us and our users, we have tried to make it as clear as possible. For your convenience, we have presented these terms in a short non-binding summary followed by the full legal terms.

Summary

The PyPI Terms of Service

Effective date: February 25, 2025

Definitions

Short version: We use these basic terms throughout the agreement, and they have specific meanings. You should know what we mean when we use each of the terms. There's not going to be a test on it, but it's still useful information.

• An "Account" represents your legal relationship with PSF. A "Personal Account" represents an individual User’s authorization to log in to and use the Service and serves as a User’s identity on PyPI. "Organizations" are shared workspaces that may be associated with a single entity or with one or more Users where multiple Users can collaborate across many projects at once. A Personal Account can be a member of any number of Organizations.
• The "Agreement" refers, collectively, to all the terms, conditions, notices contained or referenced in this document (the "Terms of Service" or the "Terms") and all other operating rules, policies (including the PyPI Privacy Notice) and procedures that we may publish from time to time on the Website. Most of our site policies are available at policies.python.org.
• "Content" refers to content featured or displayed through the Website, including without limitation: code, text, data, articles, images, photographs, graphics, software, applications, packages, designs, features, and other materials that are available on the Website or otherwise available through the Service. "Content" also includes Services. "User-Generated Content" is Content, written or otherwise, created or uploaded by our Users. "Your Content" is Content that you create or own.
• "PSF," "We," and "Us" refer to the Python Software Foundation, as well as our affiliates, directors, subsidiaries, contractors, licensors, officers, agents, and employees.
• The "Service" refers to the applications, software, products, and services provided by PSF.
• "The User," "You," and "Your" refer to the individual person, company, or organization that has visited or is using the Website or Service; that accesses or uses any part of the Account; or that directs the use of the Account in the performance of its functions. A User must be at least 13 years of age.
• The "Website" refers to the PyPI website located at pypi.org, and all content, services, and products provided by PSF at or through the Website. It also refers to python.org, pyfound.org, pythonhosted.org, and other subdomains of PSF-owned domains. Occasionally, websites owned by PSF may provide different or additional terms of service. If those additional terms conflict with this Agreement, the more specific terms apply to the relevant page or service.

Account Terms

Short version: Personal Accounts and Organizations have different administrative controls; a human must create your Account; you must be 13 or over; you must provide a valid email address; and you may not have more than one free Account. You alone are responsible for your Account and anything that happens while you are signed in to or using your Account. You are responsible for keeping your Account secure.

1. Account Controls

a. Users.

Subject to these Terms, you retain ultimate administrative control over your Personal Account and the Content within it.

b. Organizations.

The "owner" of an Organization that was created under these Terms has ultimate administrative control over that Organization and the Content within it. Within the Service, an owner can manage User access to the Organization’s data and projects. An Organization may have multiple owners, but there must be at least one Personal Account designated as an owner of an Organization. If you are the owner of an Organization under these Terms, we consider you responsible for the actions that are performed on or through that Organization.

2. Required Information

You must provide a valid email address and a username in order to complete the signup process. Any other information requested, such as your real name, is optional, unless you are accepting these terms on behalf of a legal entity (in which case we need more information about the legal entity) or if you opt for a paid Account, in which case additional information will be necessary for billing purposes.

3. Account Requirements

We have a few simple rules for Personal Accounts on the PyPI Service.

You must be a human to create an Account. Accounts registered by "bots" or other automated methods are not permitted. Machine accounts may be permitted if they pre-date features designed to fulfill similar duties such as Upload tokens (2019) and Organization accounts (2025).

• A machine account is an Account set up by an individual human who accepts the Terms on behalf of the Account, provides a valid email address, and is responsible for its actions. A machine account is used exclusively for performing automated tasks. Multiple users may direct the actions of a machine account, but the owner of the Account is ultimately responsible for the machine's actions. You may maintain no more than one free machine account in addition to your free Personal Account.
• You must be age 13 or older. PSF does not target our Service to children under 13, and we do not permit any Users under 13 on our Service. If we learn of any User under the age of 13, we will terminate that User’s Account immediately. If you are a resident of a country outside the United States, your country’s minimum age may be older; in such a case, you are responsible for complying with your country’s laws.
• Your login may only be used by one person — i.e., a single login may not be shared by multiple people. A paid Organization may only provide access to as many Personal Accounts as your subscription allows.
• You may not use PyPI in violation of export control or sanctions laws of the United States or any other applicable jurisdiction. You may not use PyPI if you are or are working on behalf of a Specially Designated National (SDN) or a person subject to similar blocking or denied party prohibitions administered by a U.S. government agency. PSF may allow persons in certain sanctioned countries or territories to access certain PSF services pursuant to U.S. government authorizations.

4. Account Security

You are responsible for keeping your Account secure while you use our Service. We offer tools such as two-factor authentication to help you maintain your Account's security, but the content of your Account and its security are up to you.

• You are responsible for all content posted and activity that occurs under your Account (even when content is posted by others who have Accounts under your Organization Account or Accounts which can upload to Projects you own).
• You are responsible for maintaining the security of your Account and password. The PSF cannot and will not be liable for any loss or damage from your failure to comply with this security obligation.
• You will promptly notify PSF if you become aware of any unauthorized use of, or access to, our Service through your Account, including any unauthorized use of your password or Account.

5. Additional Terms

In some situations, third parties' terms may apply to your use of PyPI. For example, you may be a member of an organization on PyPI with its own terms or license agreements, or you may download an application that integrates with PyPI. Please be aware that while these Terms are our full agreement with you, other parties' terms govern their relationships with you.

Acceptable Use

Short version: PyPI hosts a wide variety of packages from all over the world, and depends upon users to act in good faith. While using the service, you must follow the terms of this section, which include some restrictions on content you can post, conduct on the service, and other limitations.

Your use of the Website and Service must not violate any applicable laws, including copyright or trademark laws, export control or sanctions laws, or other laws in your jurisdiction. You are responsible for making sure that your use of the Service is in compliance with laws and any applicable regulations.

You agree that you will not under any circumstances violate our Acceptable Use Policy.

User-Generated Content

Short version: You own content you create, but you allow us certain rights to it, so that we can display and share the content you post. You still have control over your content, and responsibility for it, and the rights you grant us are limited to those we need to provide the service. We have the right to remove content or close Accounts if we need to.

1. Responsibility for User-Generated Content

You may create or upload User-Generated Content while using the Service. You are solely responsible for the content of, and for any harm resulting from, any User-Generated Content that you post, upload, link to or otherwise make available via the Service, regardless of the form of that Content. We are not responsible for any public display or misuse of your User-Generated Content.

By uploading Your Content to PyPI, you agree and affirmatively acknowledge the following:

• Your Content uploaded to PyPI is provided on a non-confidential basis, and is not a trade secret.
• You do not know of any applicable unlicensed patent or trademark rights that would be infringed by Your uploaded Content.
• You represent and warrant that You have complied with all government regulations concerning the transfer or export of any Content You upload to PyPI. In particular, if You are subject to United States law, You represent and warrant that You have obtained any required governmental authorization for the export of the Content You upload. You further affirm that any Content You provide is not intended for use by a government end-user engaged in the manufacture or distribution of items or services controlled on the Wassenaar Munitions List as defined in part 772 of the United States Export Administration Regulations, or by any other embargoed user.

2. PSF May Remove Content

We have the right to refuse or remove any User-Generated Content that, in our sole discretion, violates any laws or PSF terms or policies.

3. Ownership of Content, Right to Post, and License Grants

You retain ownership of and responsibility for Your Content. If you're posting anything you did not create yourself or do not own the rights to, you agree that you are responsible for any Content you post; that you will only submit Content that you have the right to post; and that you will fully comply with any third party licenses relating to Content you post.

Because you retain ownership of and responsibility for Your Content, we need you to grant us — and other PyPI Users — certain legal permissions, provide in subections 4 — 6 below. These license grants apply to Your Content. If you upload Content that already comes with a license granting PSF the permissions we need to run our Service, no additional license is required. You understand that you will not receive any payment for any of the rights granted in subsections 4 — 6 below. The licenses you grant to us will end when you remove Your Content from our servers.

4. License Grant to Us

We need the legal right to do things like host Your Content, publish it, and share it.

If you upload Content covered by a royalty-free license included with such Content, giving the PSF the right to copy and redistribute such Content unmodified on PyPI as you have uploaded it, with no further action required by the PSF (an "Included License"), you represent and warrant that the uploaded Content meets all the requirements necessary for free redistribution by the PSF, users of the Service, and any mirroring facility, public or private, under the Included License.

If you upload Content other than under an Included License, then you grant the PSF, its legal successors and assigns, and all other users of the Service an irrevocable, worldwide, royalty-free, nonexclusive license to reproduce, distribute, transmit, display, perform, and publish the Content, including in digital form.

This license does not grant PSF the right to sell Your Content. It also does not grant PSF the right to otherwise distribute or use Your Content outside of our provision of the Service, except that as part of the right to archive Your Content, PSF may permit third parties to mirror Your Content.

5. Contributions Under Other Licenses

Whenever you add Content with a specified license, you license that Content under the same terms, and you agree that you have the right to license that Content under those terms. If you have a separate agreement to license that Content under different terms, such as a contributor license agreement, that agreement will supersede.

"Isn't this just how it works already?"

Yep. This is widely accepted as the norm in the open-source community; it's commonly referred to by the shorthand "inbound=outbound". We're just making it explicit.

6. Moral Rights

You retain all moral rights to Your Content that you upload, publish, or submit to any part of the Service, including the rights of integrity and attribution. However, you waive these rights and agree not to assert them against us, to enable us to reasonably exercise the rights granted in subsection 4 above, but not otherwise.

To the extent this agreement is not enforceable by applicable law, you grant PSF the rights we need to use Your Content without attribution and to make reasonable adaptations of Your Content as necessary to render the Website and provide the Service.

Private Servers

Some parties may run PyPI-compatible servers that interoperate with PyPI and PyPI client software. These third-party servers are not operated by PSF and are governed by the terms (if any) established by their operators.

Copyright Policy

If you believe that content on our website violates your copyright, please contact us in accordance with our Copyright Policy. If you are a copyright owner and you believe that content on PyPI violates your rights, please contact us via our convenient DMCA form or by emailing legal@python.org. There may be legal consequences for sending a false or frivolous takedown notice. Before sending a takedown request, you must consider legal uses such as fair use and licensed uses.

We will terminate the Accounts of repeat infringers of this policy.

Abuse or excessively frequent requests to PyPI via the API may result in the temporary or permanent suspension of your Account's access to the API. PSF, in our sole discretion, will determine abuse or excessive usage of the API. We will make a reasonable attempt to warn you via email prior to suspension.

All use of the PyPI API is subject to these Terms of Service and the PyPI Privacy Policy.

Paid Services

Short version: You are responsible for any fees associated with your use of paid PyPI services. We are responsible for communicating those fees to you clearly and accurately, and letting you know well in advance if those prices change.

1. Pricing

We charge fees to host Organizations for private entities, and for support services. Our pricing and payment terms are available at https://docs.pypi.org/organization-accounts/pricing-and-payments/. If you agree to a subscription price, that will remain your price for the duration of the payment term; however, prices are subject to change at the end of a payment term.

2. Upgrades, Downgrades, and Changes

• We may immediately bill you when you register for a paid corporate Organization account.
• If you upgrade to a higher level of service, we may bill you for the upgraded plan immediately.
• You may change your level of service at any time by choosing a plan option or going into your Billing settings. If you choose to downgrade your Account, you may lose access to Content, features, or capacity of your Account. Please see our section on Cancellation for information on getting a copy of that Content.

3. Billing Schedule; No Refunds

Payment Based on Plan. Services are billed in advance on a monthly basis and is non-refundable. There will be no refunds or credits for partial months of service, downgrade refunds, or refunds for months unused with an open Account; however, the service will remain active for the length of the paid billing period. In order to treat everyone equally, no exceptions will be made.

Payment Based on Usage Some Service features are billed based on your usage. A limited quantity of these Service features may be included in your plan for a limited term without additional charge. If you choose to use paid Service features beyond the quantity included in your plan, you pay for those Service features based on your actual usage in the preceding month. Monthly payment for these purchases will be charged on a periodic basis in arrears.

Invoicing. For invoiced Users, User agrees to pay the fees in full, up front without deduction or setoff of any kind, in U.S. Dollars. User must pay the fees within thirty (30) days of the PSF invoice date. Amounts payable under this Agreement are non-refundable, except as otherwise provided in this Agreement. If User fails to pay any fees on time, PSF reserves the right, in addition to taking any other action at law or equity, to (i) charge interest on past due amounts at 1.0% per month or the highest interest rate allowed by law, whichever is less, and to charge all expenses of recovery, and (ii) terminate the applicable order form. User is solely responsible for all taxes, fees, duties and governmental assessments (except for taxes based on PSF's net income) that are imposed or become due in connection with this Agreement.

4. Authorization

By agreeing to these Terms, you are giving us permission to charge your on-file credit card or other approved methods of payment for fees that you authorize for PyPI.

5. Responsibility for Payment

You are responsible for all fees, including taxes, associated with your use of the Service. By using the Service, you agree to pay PSF any charge incurred in connection with your use of the Service. If you dispute the matter, contact PSF Support. You are responsible for providing us with a valid means of payment for paid Accounts. Free Accounts are not required to provide payment information.

Cancellation and Termination

Short version: You may close your Account at any time. If you do, we'll treat your information responsibly.

1. Account Cancellation

It is your responsibility to properly cancel your Account with PyPI. You can cancel your Account at any time by going into your Settings in the global navigation bar at the top of the screen. The Account screen provides a simple, no questions asked cancellation link. We are not able to cancel Accounts in response to an email or phone request.

2. Upon Cancellation

We will retain and use your information as necessary to comply with our legal obligations, resolve disputes, and enforce our agreements, but barring legal requirements, we will delete your full profile and the Content of your Project(s) and/or Organizations immediately upon cancellation or termination (though some information may remain in encrypted backups). This information can not be recovered once your Account is canceled. Activity logs reflecting user actions taken on Projects and Organizations are retained as long as reasonably required.

Upon request, we will make a reasonable effort to provide a Account owner with a copy of your lawful, non-infringing Account contents prior to Account cancellation, termination, or downgrade. You must make this request before cancellation, termination, or downgrade.

3. PSF May Terminate

PSF has the right to suspend or terminate your access to all or any part of the Website at any time, with or without cause, with or without notice, effective immediately. PSF reserves the right to refuse service to anyone for any reason at any time.

This section does not affect your non-waivable rights.

2. Legal Notice to PSF Must Be in Writing
