One Thing is an Ardenholt program operated by Ruzylo Cloud, LLC. This sheet describes what we hold, why, and your rights over it. It is short for a reason: your tasks are written on your device and stay there.
What we collect
- Your email address — only if you enter the register. Used to write to you about One Thing, and nothing else.
- License keys and receipts — only once a price exists and you buy, so that we can prove what you own when you unlock the app.
- An authentication identifier — only if you choose to sign in. With Sign in with Apple we store the opaque identifier Apple gives us and never receive your real address unless you share it.
- Standard server logs — IP address, user agent, request path, kept no longer than thirty days for security and debugging.
- Payment details — handled entirely by our payment processor. We never see or store a card number.
What we do not collect
Your tasks. The errand, the email you have been avoiding, the thing you wrote down at 1am and would not want read back. Your answers to the triage questions, what you finished, what you passed on, and how long any of it sat there.
All of it is written on your device and stays there. There is no sync, no backup of it on our side, and no server of ours holding it, which means we cannot read it, cannot restore it, and cannot be made to hand it over. If a sync feature is ever built it will be opt-in, and it will say so plainly before it moves a single line.
What we will not do
- We do not sell your data. Ever.
- We do not run third-party advertising trackers.
- We do not use anything you dump to train any model.
- We do not share your data with brokers.
- We do not build a profile of how productive you are, for us or for anyone else.
Where the little of it lives
Register addresses, and later any receipts and license keys, are stored on our hosting provider's infrastructure in the United States. Our payment processor stores payment data under its own policy, and Apple stores Sign in with Apple credentials under Apple's.
A word about what a task list would reveal
A complete list of everything a person is avoiding is a remarkably intimate document — medical appointments, debts, the conversations they have not had. That is the strongest argument we know for not holding one, and it is why the pile never reaches us rather than reaching us under a promise to be careful with it.
Your rights
All four go to [email protected]. Because your pile is not ours, an export from us will be short: an address, and later perhaps a receipt and a key.
- Access — write to us and we send a copy of everything we hold on you within thirty days.
- Deletion — the same, and we delete within thirty days unless a law requires us to keep a billing record.
- Correction — the same address, or change it in the app where that applies.
- Portability — exports come as JSON or CSV.
Children
One Thing is not intended for children under 13, or under 16 in the EU, and we do not knowingly collect data from them.
Changes
If this sheet changes materially we will update the effective date at its head and write once to anyone on the register.
