Sustainer is built for parents who already have too much on their plate. We collect as little as we can, and we never sell it.
- Waitlist: your email, so we can tell you when early access opens.
- Feedback form: the answers you choose to give, plus your email only if you add it.
- Demo: your tasks stay on your device. We log which screens and buttons are used, not what you type.
- Never: we don't sell your data, share it for advertising, or add you to other lists.
- Your call: email sustainerapp@gmail.com and we'll delete your data.
What we collect, and why
Early-access waitlist (sustainerapp.com)
When you join the waitlist, we save your email address, the date you joined, and, if the link you used had one, a short tag showing where you found us (for example "instagram" or "demo"). We use your email only to tell you about early access to Sustainer. We don't save your IP address with your sign-up.
Feedback form (sustainerapp.com/feedback)
Every question is optional. We save the answers you give, and the same "where you found us" tag. Your email is saved only if you type it in, and we use it only for what you check: joining the early-access list, a short call, or both. We read your answers to decide what to build, change, or cut.
Demo (demo.sustainerapp.com)
The tasks you type in the demo are stored in your own browser, on your device. They aren't sent to us, and other visitors can't see them. Clearing your browser data, or choosing "Start the demo over", removes them.
To learn which parts of the demo help, we record basic usage: a random session ID, which screens you open and buttons you tap, the bucket you choose, and how you said you're feeling if you answer that prompt. We don't record the text of your tasks.
The demo is built and hosted with Emergent, which runs its own product analytics on apps it hosts. That analytics can record how the page is used, such as clicks, page views, and session replays. It's operated by Emergent under their own privacy policy.
Our website
sustainerapp.com doesn't use cookies, ad trackers, or analytics. Our fonts load from Google Fonts, so Google receives your IP address when the page loads, as it does for any site using their fonts.
Who helps us run Sustainer
We use a few service providers to store and process data on our behalf. They can only use it to provide their service to us.
| Amazon Web Services | Hosts sustainerapp.com and stores the waitlist, in the United States (Ohio). |
|---|---|
| Tally | Runs the feedback form and stores its answers. |
| Emergent | Builds and hosts the demo, stores its usage log, and runs its own analytics. |
| Delivers our email (sustainerapp@gmail.com) and our website fonts. |
How long we keep it
We keep your waitlist email until early access opens and you've had a chance to join, or until you ask us to delete it, whichever comes first. We keep feedback for as long as it's useful for deciding what to build, and we delete it if you ask.
Your choices
- See or delete your data: email sustainerapp@gmail.com from the address you signed up with, and we'll reply within 30 days.
- Stop hearing from us: reply "unsubscribe" to any email we send, and we'll remove you.
- Skip anything: every feedback question is optional, and you can use the demo without giving us an email at all.
Depending on where you live, you may have additional rights over your personal data, such as the right to access, correct, or delete it, or to object to how it's used. Email us and we'll help.
Children
Sustainer is for adults. We don't knowingly collect information from children under 13. If you think a child has given us their information, email us and we'll delete it.
Changes
If we change how we handle your data, we'll update this page and the date at the top. If a change is significant, we'll email the people on our list before it takes effect.
