An anonymous survey means you do not collect anything that identifies the person: no name, no email, no sign-in, and no hidden field that carries an ID. Most free tools can do this, but the tool alone does not decide it; your settings do. Disclosure: we make Qwenvo, so it is listed first. No tool, including ours, can promise perfect anonymity.
What anonymous really means
People say anonymous when they mean three different things. Be clear which one you are promising:
- Anonymous: you collect no identifying data at all, directly or indirectly.
- Confidential: you know who answered, but you promise not to share it.
- Pseudonymous: respondents carry a code, and only you can match it to a person.
Small groups are the trap. If five people work in a team and one answer says the respondent is the only designer, nothing in the settings saves you. Keep demographic questions broad or leave them out.
How we ranked the tools
- No sign-in needed to answer.
- Control over what is collected, such as optional or removable fields.
- Retention: can you delete answers on a schedule?
- Clarity about what the tool records, and a privacy page you can read.
- Price.
1. Qwenvo
Best for: employee pulse checks and feedback boxes. Respondents do not need an account. The form collects only the fields you add.
- Do not add name, email, phone, or any hidden field that carries an ID.
- Leave out the optional Respondent's country block. It is only there if you add it.
- Leave off email verification and confirmation emails, since both need the respondent's address.
- Set data retention in Settings so answers are deleted after N days.
- Use AI triage with care: it reads the text of answers, so free-text comments are summarised, and routing sends the summary to email or Slack. Switch it off if the comments could identify someone.
Start with the employee satisfaction survey or employee wellbeing survey template and delete any identifying questions. Watch out for: we cannot claim anything about network-level logs for any tool. Read our privacy page and your own policy before promising anonymity.
2. Google Forms
Best for: quick anonymous polls. Watch out for: if you require a Google sign-in, such as for file uploads, answers are tied to a person. Check the form's response-collection settings before you promise anything.
3. Microsoft Forms
Best for: anonymous surveys inside a Microsoft 365 organisation, if you configure it for anyone to respond. Watch out for: depending on how you configure it, answers may be tied to a name; check Microsoft's documentation.
4. Tally
Best for: simple anonymous forms with a clean design. The free plan has unlimited submissions. Watch out for: data retention is a Business feature, $89 a month or $890 a year.
5. Formbricks
Best for: anonymous surveys where you want to host the software. The Community Edition is free to self-host (AGPLv3). Watch out for: self-hosting makes you responsible for the server. See pricing.
Where Qwenvo falls short
Qwenvo is hosted in the United States and has no HIPAA offering. For a sensitive whistleblowing channel, use a dedicated service with the legal protections you need.
Wording that keeps the promise
The words on the first page matter as much as the settings. Say exactly what you collect and what you do not, in plain sentences:
- State that you do not ask for names or email addresses.
- State who will read the answers, and in what form, such as only totals and grouped comments.
- State the smallest group you will report on, so no one can be singled out.
- State when the answers will be deleted.
- Ask whether comments may be quoted, and leave the default as no.
Never promise what you cannot check. If you are unsure about a setting, test the form yourself as a respondent and look at the row that arrives.
Questions people ask
Is a free survey really anonymous?
It is as anonymous as what you collect and who you tell. Fields, sign-ins and small groups decide it.
Should I use the Respondent's country block?
Only if you need it. It is optional, and in a small team it can narrow down who answered.
How long should I keep anonymous answers?
As short as your purpose allows. Set a retention period before launch. See data retention.
