Privacy policy
Haiku Grove is a place to write haiku with strangers. We collect as little as we can to run it, we don’t sell your information, and you can delete your account at any time.
What we collect
- Your email address, to sign you in. If you sign in with Apple, Google or Facebook, that service tells us your email address and an account ID. Google and Facebook may also send your name and profile picture. We don’t display or use them, because Haiku Grove uses your pen name.
- Your birth month and year, to check Haiku Grove is right for your age and to give under-18s extra protection. It is kept privately and never shown to anyone.
- What you choose to add: your pen name, and optionally a short bio and (if you’re 18 or over) a city.
- What you do in Haiku Grove: the lines you write, comments, hearts, reshares, the poets you follow and block, reports you make, and messages you send.
- Basic technical information that any website or app sends, such as your IP address, kept by our hosting providers to keep the service secure.
What other people can see
- Public: your pen name, city and bio, the lines you write, your comments, and your hearts, reshares and follows.
- Private: your email address, your reports and blocks, and your messages. Messages can only be read by you and the poet you’re writing to. They are stored on our servers and are not end-to-end encrypted.
How we use it
- To run Haiku Grove: sign you in, save poems, keep the 30-minute writing time, deliver messages.
- To keep it kind and safe: block swear words, act on reports, and stop abuse.
- We don’t sell your information, and we don’t use it to target advertising. If we add ads in future, they will be family-safe and not personalised unless you agree.
Who helps us run Haiku Grove
- Supabase stores the database and handles sign-in (servers in Singapore).
- Cloudflare hosts this website.
- Google Fonts and jsDelivr deliver fonts and code to the website, so they see your IP address when pages load.
- Anthropic (Claude) writes lines for our AI poets, which finish poems nobody has picked up for a while. It is sent the earlier lines of that poem only, never who wrote them or anything about you.
- Apple, Google and Facebook, only if you choose to sign in with them.
Your browser and phone
The website keeps your sign-in, theme choice and unfinished drafts in your browser’s storage. The app keeps the same on your phone. We don’t use advertising or tracking cookies.
Ages 13 and up, with extra care for under-18s
Haiku Grove is for people aged 13 and older. If someone tells us they are under 13 when they sign up, we delete their new login straight away and keep nothing. If we learn that someone under 13 has an account, we delete it.
- Phone numbers, email addresses, links and social media handles can’t be posted anywhere on Haiku Grove, by anyone.
- Poets under 18 don’t show a city, and their messages are off unless they choose to switch them on. Even then, only poets who follow each other can message.
- Anyone can report a poet who may be under 13. Two reports pause that account until a moderator checks it.
Deleting your account
You can delete your account yourself at any time:
- Website: sign in, open your profile (top right), scroll to the bottom and choose Delete my account.
- iPhone app: open the Me tab, tap the menu (•••) and choose Delete account.
Deleting removes your sign-in, email address, messages, comments, hearts, reshares, follows, blocks, reports and unfinished poems straight away. Lines you wrote in finished poems stay, credited to “Departed poet”, so the two other poets keep their poem. Your pen name, city and bio are removed from them.
If you signed in with Facebook, you can also remove Haiku Grove under Facebook Settings → Apps and Websites. That stops Facebook sharing anything new with us. To delete what we already hold, delete your Haiku Grove account as described above.
Changes
If we change this policy we’ll update the date at the top. If a change matters, we’ll tell you in the app.
