Terms of Use

Siamang Studio and Siamang Cloud are operated by Siamang Labs LLC, a Wyoming limited liability company (Siamang, we, us), the team behind the source-available siamang research-as-code engine.

These Terms of Use (the Terms) govern your use of Siamang Studio, Siamang Cloud, the surveys they host, and the websites and services around them (together, the Services). The following documents are part of these Terms:

• the Acceptable Use Policy: what the Services may not be used for, and how we handle reports;
• the Data Processing Agreement: how we process the personal data in your surveys and projects on your behalf;
• the list of subprocessors.

The Privacy Policy explains how we handle personal data for which we are responsible ourselves.

By creating an account, or by using the Services for an organization, you accept these Terms. When you create an account in Siamang Studio, we record which version of the Terms you accepted and when. If you do not agree, do not use the Services.

1. What the Services are

The siamang engine

The engine is a Python library for defining questionnaires, running surveys and analyzing responses. It is source-available under the license terms published with it, which currently include PolyForm Noncommercial 1.0.0 (free for non-commercial use) and a separate commercial license. These Terms govern the hosted Services; they do not replace the engine license that applies when you run the engine yourself.

Siamang Studio

Siamang Studio (studio.siamang.org) is a hosted platform for building surveys without writing code. Every questionnaire you build is stored as a document and compiled by the engine into Python, which you can download at any time. Studio lets you:

• build questionnaires with logic, quotas, randomization, a codebook and a theme;
• publish surveys at study.siamang.org and collect responses, including from a panel provider you contract with;
• invite respondents by email from a contact list you upload, and remind those who have not answered;
• analyze responses with visual analysis flows, and produce reports and live dashboards;
• keep every Save as a version, and download the generated code, a research bundle and a Methods draft;
• deposit a research bundle in a repository such as Zenodo or OSF with your own credentials;
• work with teammates in an organization.

Siamang Cloud

Siamang Cloud (app.siamang.org) is a hosted platform for people who write their surveys as code in a Git repository: it validates and previews projects, deploys live surveys, runs analysis in a sandbox and exports results.

Features differ by product and plan, and change during the beta.

Code you download

Code the Services generate for you runs on the siamang engine and is subject to the engine license. A paid plan includes a commercial license of the engine for running the code generated from your projects. On the Free plan, the engine license’s non-commercial terms apply to that code. Your own content inside it (question texts, codebooks, analysis definitions) stays yours (section 5).

2. Accounts and eligibility

You must be at least 16 years old to hold an account, or older if the law where you live requires it to accept these Terms.

If you use the Services for an organization, such as your employer or university, you confirm that you may accept these Terms on its behalf, and “you” includes that organization.

You can sign in with an email address and password, or with Google or another sign-in provider we offer; your use of that provider is subject to its own terms. You agree to:

• give accurate account information and keep it up to date;
• keep your password, sessions and API keys secure;
• tell us at support@siamang-team.org if you think someone else is using your account.

You are responsible for what is done through your account unless the law says otherwise.

Each email address gets one free trial. Do not create accounts or organizations to get further trials, or to get around a plan’s limits.

Organizations

Projects belong to an organization. Its owners and admins manage members, roles and settings; only an owner buys plans. If you join an organization run by someone else, its owners and admins can access, export and delete the work you do in its projects, including after you leave.

3. Beta status and changes

The Services are in open beta. That means:

• features can be added, changed or removed, and limits can change;
• there may be errors, and data can be lost despite our backups, so keep your own exports of anything important;
• there is no service-level agreement and no guaranteed uptime;
• we may stop the Services for maintenance, or for a short time make Studio read-only or pause publishing or mailings to handle an incident; Studio shows a banner while we do;
• support is by email, on a reasonable-efforts basis.

If we close a Service, we will tell organization owners by email at least 30 days before it closes, keep export working until then, and refund any prepaid fees for the time after it closes.

4. Plans, trial and payment

This section describes Siamang Studio. Siamang Cloud has its own plans and prices; see “Siamang Cloud” at the end of this section.

Plans and prices

Studio is priced per organization, not per person or per response:

What each plan includes, and its limits, are shown in Studio under Settings → Billing. Prices are in US dollars and exclusive of any applicable taxes. Payments are processed by Stripe. Only an owner of the organization can buy a plan.

The trial

• When you sign up, the organization created for you gets a 30-day trial of the Pro plan. No card is needed. Organizations you create later start on the Free plan.
• During the trial, email invitations are not available, and custom JavaScript and CSS can be written and previewed but are not published. Buying any paid plan removes these restrictions.
• When the trial ends, the organization moves to the Free plan, or to the plan you bought to start after the trial. Nothing is paused and nothing is deleted. Free’s limits apply from then on: for example, a survey stops accepting new responses once its project has 1,000 completed responses, and an organization above a count limit (projects, members) keeps what it has but cannot add more.

Monthly subscriptions

• Plus and Pro are monthly subscriptions. They renew automatically each month, at the price then in force, until you cancel.
• If you subscribe during the trial, the first charge is made when the trial ends; in roughly the last two days of a trial, it is made at once. A Pro subscription continues the Pro trial without a break; a Plus subscription starts when the trial ends.
• Moving from Plus to Pro takes effect at once, and the difference for the rest of the current billing period is charged at once.
• To move to a lower plan, cancel, and buy the lower plan once the organization is on Free.

Year offers

During the open beta we offer 12 months of Plus for $240 and 12 months of Pro for $900, each as a single payment. A year offer:

• runs for 12 months, counted from the end of a running trial, or from the purchase if no trial is running;
• is not a subscription and does not renew: when it ends, the organization moves to Free unless you subscribe;
• can be bought until the deadline shown in Billing.

Canceling

An owner cancels a subscription under Settings → Billing → Manage billing, which opens Stripe’s customer portal. A canceled subscription runs to the end of the period already paid, and the organization then moves to Free. A subscription bought during the trial and canceled before the trial ends is never charged.

Moving to a lower plan deletes nothing. Features above the new plan stop being available.

Failed payments

If a charge fails, the organization’s owners receive an email, and Studio shows them a notice with a link to update the card. Stripe tries the charge again over the following days, and nothing changes in the meantime. If every retry fails, the subscription ends and the organization moves to Free; its projects and data are kept.

Refunds

Payments are not refundable, except that:

• if a purchase overlaps one you already have (for example, a year offer bought while a subscription was running), we end the extra one and refund it;
• if you think you were charged by mistake, write to support@siamang-team.org within 30 days of the charge, and we will refund a charge that was made in error;
• we refund the unused part of prepaid fees when we close a Service (section 3), when you close your organization over a change to these Terms (section 13), or when you stop using a Service over a new subprocessor you objected to (Data Processing Agreement, section 6);
• if you are a consumer in the European Union or the United Kingdom, you may withdraw from a purchase within 14 days of making it by writing to support@siamang-team.org. If the plan has already started, we refund the price minus the part for the days already used; if you have not been charged yet, nothing is charged;
• nothing in these Terms limits a right of withdrawal or refund that the law where you live gives you and that cannot be waived.

Refunds go back to the original payment method through Stripe.

Price changes

A new price applies to new purchases from the day it is published. For a running subscription, a higher price applies from the first billing period that starts at least 30 days after we email the organization’s owners about it, and you can cancel before then. A year already paid for is not affected.

Corporate

The Corporate plan is arranged with us directly. Where a signed Corporate agreement differs from these Terms, the agreement applies.

Siamang Cloud

Siamang Cloud’s plans, prices, limits, trial and pre-orders are shown on the Siamang Cloud page and in Cloud, and what you are shown at checkout applies to your purchase. Where those say nothing, the rules above on subscriptions, year offers, canceling, failed payments, refunds and price changes apply to Cloud too. When a Cloud trial ends, you can subscribe or stay on the Free plan; your data and surveys are kept either way.

5. Your content and respondent data

Ownership

As between you and Siamang, you keep your rights in the questionnaires, analysis flows, scripts, files, contact lists, datasets, responses, reports and other content you put into or create with the Services (Your Content).

License to run the Services

You give Siamang a limited, non-exclusive license to host, store, copy, transmit, process, compile, run and display Your Content only as needed to provide, secure and maintain the Services for you: validation, code generation, previews, publishing, response collection, email delivery, analysis, live dashboards, collaboration, backups and export. This license ends when Your Content is deleted, subject to the backup period in section 12.

No training on your content

We do not use your questionnaires, flows, scripts, contact lists, responses or other project content to train machine-learning models. We may use aggregate or de-identified information about how the Services are used to run, secure and improve them. The AI assistant is not connected to any provider during the beta (section 8).

Who is responsible for personal data

For the personal data in your surveys, responses, contact lists, uploaded files and projects, your organization is the controller and Siamang is your processor. The Data Processing Agreement applies to that processing automatically as part of these Terms, and where it differs from these Terms, it prevails. For account, billing, support and security data, Siamang is the controller, as described in the Privacy Policy.

Your responsibilities as survey operator

You decide what a survey collects, from whom and why. You are responsible for:

• the lawfulness and appropriateness of your survey and of the contact lists you upload;
• having a lawful basis for collecting and using personal data;
• giving respondents the privacy notice the law requires, including what the survey keeps in their browser, that answers reach you page by page before they submit, and which other services the survey uses (for example the captcha, or media you embed);
• getting consent where it is required, and protecting any sensitive or special-category data you choose to collect;
• answering respondents’ requests about their data, including requests to delete their answers;
• your agreements with any panel provider that supplies respondents;
• the laws that apply to your research and your organization.

Deposits in external repositories

When you deposit a research bundle in Zenodo, OSF or a similar repository, the deposit is made in your name, with your credentials and on your instruction. A published deposit and its DOI follow that repository’s rules and are generally permanent; we cannot recall or delete them for you.

6. Acceptable use

You must follow the Acceptable Use Policy. In short: no phishing or collecting passwords or payment details, no malware, no spam, no illegal content, no harassment, no deceptive surveys, no misuse of respondents’ data, and no attacks on or abuse of the Services. We may apply technical limits, such as rate limits, quotas and storage, execution and email limits, to keep the Services secure and available.

Email invitations

Studio sends survey invitations and reminders to the contacts you upload, from a sending domain that all customers share, so one misused list harms every customer. When you use this feature:

• you may only upload people who agreed to be contacted about your research, or with whom you have an existing relationship that makes the contact lawful and expected; purchased, scraped or harvested lists are not allowed;
• you confirm this each time you import a list, and we record that confirmation;
• every email carries an unsubscribe link and a one-click unsubscribe header, which you may not remove or work around;
• an address that unsubscribes, bounces permanently or reports the email as spam is not emailed again from that project;
• we pause a mailing automatically, and new mailings of the organization, when its spam complaint rate reaches 0.05% or its bounce rate reaches 2% (with at least three bounces), and keep them paused until we have reviewed the list with you;
• invitations are available on paid plans only, not during the trial; volumes are limited per day and per month by plan, and an organization’s first mailing is limited in size;
• emails are sent from our address; you set the sender name and the reply-to address.

Custom JavaScript and CSS, and the shared survey address

On a paid plan you can add custom JavaScript and CSS to a survey. That code runs in respondents’ browsers, inside the survey page, under your responsibility.

All Studio surveys are served from one web address (study.siamang.org) and share the respondent’s browser storage for that address. Custom JavaScript in one survey can therefore technically read what other surveys keep in the same browser, such as an unfinished draft of answers. We do not give each survey its own address; we limit custom code to paid plans instead. By adding custom code you accept this design, and you agree that your code will not:

• read, change or send data that belongs to another survey;
• track respondents beyond your survey, fingerprint devices, or load trackers without a lawful basis and a notice;
• send data anywhere your privacy notice does not disclose;
• hide or disable the survey’s Report abuse link or the unsubscribe mechanism, or interfere with the survey runtime or our infrastructure.

Breaking these rules is a serious breach of these Terms.

Public links

A survey link, a share-preview link and a live dashboard share link can be opened by anyone who has them, without signing in. You are responsible for what a dashboard shows, for whom you give a link to, and for revoking a link when it should no longer be public.

7. Reports, suspension and takedown

Anyone can report a survey through the Report abuse link at the bottom of every survey page, which opens studio.siamang.org/report, or by email to support@siamang-team.org. The Acceptable Use Policy describes how we review reports.

We may close a survey, pause an organization’s mailings, freeze an organization (which pauses all its live surveys), or disable an account when that is reasonably needed because:

• you break these Terms or the Acceptable Use Policy;
• your use puts respondents, other customers, the shared survey address or the Services at risk;
• the law or a competent authority requires it.

In urgent cases, such as phishing, malware, illegal content or harm to respondents, we act first and tell you right after. Otherwise we write first and give you time to fix the problem. Either way, we tell the organization’s owners what we did, which rule it was based on, and how to appeal: reply to our email, and someone who was not involved in the decision will review it where our team’s size allows. A takedown does not delete your data. We may end the account of someone who breaks these Terms seriously or repeatedly.

8. Third-party services and the AI assistant

The Services work with products you choose to use: sign-in providers, connectors you configure, panel providers, repositories you deposit into, and media you embed. Those services are governed by their own terms and privacy policies, and we are not responsible for them except where the law says otherwise.

Siamang Studio has an AI assistant for reviewing and drafting wording. During the beta it is not connected to any model provider: it sends no text outside Siamang, and an owner cannot turn it on. If we connect a provider, we will add it to the list of subprocessors and tell account holders at least 30 days in advance, and we will update these Terms to say what it sends and what its suggestions are for.

9. Security

We protect the Services with the measures described in the Privacy Policy. No online service can be perfectly secure or uninterrupted.

You are responsible for keeping independent copies of important data and for protecting your passwords, API keys, project secrets, share links and organization access, including removing people who leave.

If you find a security vulnerability in the Services, report it to support@siamang-team.org (also listed in our security.txt) instead of exploiting it or publishing details that would put users at risk. The Acceptable Use Policy describes good-faith security research.

10. Disclaimer of warranties

To the maximum extent permitted by law, the Services are provided “as is” and “as available”, without warranties of any kind, whether express, implied or statutory, including implied warranties of merchantability, fitness for a particular purpose, title and non-infringement.

We do not warrant that a Service will be uninterrupted, error-free or completely secure, or that analyses, generated code, statistical results, Methods drafts, assistant suggestions or other outputs will be accurate, complete or suitable for your purposes. You are responsible for checking outputs before you rely on them.

Nothing in these Terms excludes warranties or rights that cannot lawfully be excluded.

11. Limitation of liability

To the maximum extent permitted by law, Siamang Labs LLC and its officers, members, employees and contributors will not be liable for indirect, incidental, special, consequential, exemplary or punitive damages, or for loss of profits, revenue, goodwill, business opportunity or data, arising out of or relating to the Services.

To the maximum extent permitted by law, our total liability for all claims arising out of or relating to the Services will not exceed the greater of:

1. the amount you paid Siamang Labs LLC for the Services in the 12 months before the event giving rise to the claim; or
2. US$100.

These limits do not apply to liability that cannot lawfully be limited or excluded.

12. Ending the agreement and what happens to your data

Leaving

You can stop using the Services at any time. An owner can cancel a paid plan as described in section 4. Owners and admins can delete projects in Studio. Deleting an account, or a whole organization, is not yet a button in Studio; for this, and for anything you cannot delete yourself in Siamang Cloud, write to support@siamang-team.org from the address you signed up with. We confirm the request is yours, complete it within 30 days and tell you when it is done. If you are the only owner of an organization, tell us whether to delete the organization too or who should become its owner.

Your data

• Export at any time. In Studio, on every plan, you can export responses (CSV, Excel, SPSS, Stata, Parquet), reports, the generated code and the research bundle.
• Deleted projects. In Studio, a deleted project stays in Recently deleted for 30 days, where its owners and admins can restore it. After that it is erased for good. You can ask support to erase it sooner.
• Accounts and organizations deleted at your request are removed from our live systems.
• Backups. Copies of deleted data can remain in our backups for up to 120 days after each backup was taken. Backups are restored only as a whole, to recover the Services after a failure.
• If we end your account under section 7, we give the organization’s owners a chance to export their data where the law and the safety of others allow, and then delete it as described above.

Sections that by their nature should survive the end of the agreement, including ownership, disclaimers, limitation of liability and governing law, continue to apply.

13. Changes to these Terms

We will update these Terms as the Services evolve, and change the date at the top of this page.

If a change reduces your rights or adds to your obligations, we will email account holders at least 30 days before it takes effect, unless the law or a security need requires it sooner. Other changes take effect when published. If you keep using the Services after a change takes effect, the updated Terms apply. If you do not agree, stop using the Services and ask us to delete your data; if you close your organization over such a change before it takes effect, we refund the unused part of any prepaid period.

14. Governing law and disputes

These Terms are governed by the laws of the State of Wyoming, USA, without regard to conflict-of-laws principles.

Subject to any mandatory rights or venue rules where you live, disputes arising out of or relating to these Terms or the Services will be heard by the state or federal courts having jurisdiction in Wyoming.

Nothing in this section removes consumer, privacy or other rights that the law does not allow you to waive.

15. General terms

If any provision of these Terms is held unenforceable, the rest continue in effect to the extent permitted by law. Our failure to enforce a provision is not a waiver of our right to enforce it later.

If you send us suggestions or feedback, we may use them without obligation to you; this gives us no rights in Your Content.

You may not assign these Terms without our consent where consent is legally required. Siamang Labs LLC may assign them as part of a merger, reorganization, sale of assets or similar transaction, subject to applicable law.

These Terms, with the documents listed at the top of this page, are the whole agreement about the Services. If they conflict, a signed Corporate agreement comes first, then the Data Processing Agreement for the processing of personal data, then these Terms.
