Siduri Privacy Policy
Effective 12 November 2026
Siduri is a personal task app: you say or type what you need to do, and it organizes it into tasks and reminds you. This page says what Siduri keeps, why, who handles it, and for how long. Questions go to tim@ayuniapp.com.
What Siduri keeps
- Your account: the email address you sign in with, or the one Sign in with Apple gives, which can be a private relay address, and an account id.
- What you add: the text of what you say or type into the app, and the tasks, lists, projects, notes and keywords made from it.
- Your settings: the app's language, your time zone, your choices for reminders, the daily plan and quiet hours, and a token that lets the app send notifications to your phone.
- Problem reports: where in the app something went wrong and what kind of error it was. They never include the text of your tasks.
What you say is turned into text by your iPhone's own speech recognition, from Apple. Siduri does not record or keep audio.
How it is used
- To organize what you say or type into tasks, with a day, a time and a project.
- To send the reminders and the daily plan you choose in Settings.
- To keep the app working and fix problems.
Siduri does not sell your data, show ads, or track you across other apps or websites.
Who handles it
- Google Firebase stores your data and runs the app's server, on Google Cloud servers in Belgium.
- OpenAI receives the text of each entry, with the names of your projects and your open tasks when they are needed to understand it, and returns how to organize it. Under OpenAI's terms for its API, this data is not used to train its models. OpenAI may keep it for a limited time to watch for abuse.
- Apple provides Sign in with Apple, the speech recognition on your iPhone, and the delivery of notifications.
Siduri asks for your permission before anything you say or type is sent to OpenAI for the first time. Each of these services handles the data under its own terms, and must protect it at least as well as this policy describes.
How long it is kept
- A finished or dropped task is deleted for good 90 days after it was finished. What you said goes with it, once no task made from it remains.
- Everything else is kept while you have the account.
- Deleting your account, in Settings, deletes all of it at once, for good.
Your choices
- You can change or delete any task in the app, and delete your account in Settings.
- You can turn reminders and the daily plan off in Settings.
- To ask for a copy of your data, or anything else about it, write to tim@ayuniapp.com. A copy is sent within a month.
Children
Siduri is not meant for children under 13, and does not knowingly keep data about them.
