Sigmer is a research platform for studies with people: plan a study, clear ethics, build it, recruit participants, collect responses, analyse the data and write the paper in one workspace.

Delivery
State the question, design and hypotheses once, and the proposal and analysis plan quote them.
Your question
Does a regular bedtime improve next-day mood?
Protocol
We will recruit 120 participants and randomise them to a regular or a free bedtime for 14 days.
Write the application and consent form from templates, and publish only studies that keep the consent form's promises.

Methods
Following earlier diary work [1], we recruited 120 participants and followed them for 14 days.

Answers leave the participant's browser over an encrypted connection.
The participant's browser seals the answers to your team's keys before sending them.
The Sigmer vault
The vault encrypts them at rest under a key made for this study, which Sigmer manages.
The vault stores the sealed answers as it received them, and cannot open them.
