Privacy at Inkido

Last updated October 25, 2026

Inkido teaches kids aged 8 to 12 to write. Accounts belong to a parent or guardian, and we collect as little about children as we can. This page explains what we keep, who helps us run Inkido, and how to delete it all.

What we keep

• The parent’s email and password. Used to sign in and to reach you about the account. Passwords are stored hashed by our sign-in provider; we never see them.
• The writer’s first name or nickname. Shown only inside your own account. We never ask for a child’s email, photo, full name, school or location.
• Lesson progress. XP, stars, streaks, badges, writer levels, which unit chests have been opened and where each lesson was left off. For Word Gym, each word the writer has practised, how many times in a row they got it right and when it comes back for review. For Streak Shields and daily quests, how many shields the writer holds, which missed days a shield covered or the writer won back, and which quests were finished each day. For each lesson and Word Gym workout, when it started and finished and which answers were right, so the points it earns are worked out on our server. The sentences written in Level Up are checked there too but aren’t kept with these results.
• A writer name and animal. Writers pick a generated name such as BraveOtter42 from words we choose, so it can’t contain personal details. Other writers see only this name and animal, never the real name.
• Friends. Who asked whom, and each parent’s approval or decline. A friendship only starts after both parents approve. There is no chat or messaging on Inkido. A parent can turn friends off, remove any friend, and see every request in Parent settings.
• Weekly leagues. Each week a writer who earns XP joins a group of up to 30 writers in the same league from across Inkido. Writers in the group see each other’s writer name, animal and weekly XP, never real names, and can’t message or friend each other from the board. A parent can turn this off in Parent settings, and then writers who aren’t friends see only a label like “Silver writer 12”.
• Sharing with friends. With sharing on, a writer can send approved friends fixed cards about a new badge, level, collectable, league or finished unit, and friends get a notice when a friend passes them on the weekly board. A parent can turn sharing off in Parent settings.
• Stories in the Story Book. Each unit ends with a Story Challenge, and the story a writer finishes (its title and sentences) is saved, one per unit. Only the writer and their own parent can read stories: friends and other writers never see them, and they are never shared or published. A parent can print them from Parent settings. Writing a unit’s story again replaces the old one.
• The weekly report. Every Sunday evening the parent gets one email per writer about their week: lessons and stories finished, how many minutes their lessons took (timed by the lessons themselves, and only lessons that earned XP count), their streak, new words, the skill practised, their best sentence of the week and a question for dinner. Writers never get email. To pick the best sentence, we keep one sentence per writer per week, the one Inky rated highest, exactly as written, and delete it after 8 weeks. We also note which weeks were emailed so nobody gets the same week twice. Every email has a link to stop them, and the parent can turn the report off or on in Parent settings. The report also shows each writer’s weekly goal (2, 3 or 5 lessons), which the parent picks when signing up and can change in Parent settings.
• The taster lesson. Anyone can try a short lesson from the home page without an account. Nothing from it is sent to us: the score (how many answers were right, and the day) stays in that browser for 7 days. If a parent then signs up and signs in on the same device, the score is sent once to add its XP to the new writer, and then removed from the browser. Inky’s AI isn’t used in the taster.
• Grade and starting level. If the parent picks one, the writer’s school grade (3 to 7), and the level the writer starts at (Grades 3 and 4, 5 and 6, or 7). It sets how hard the words are and how Inky reads the writing. The parent can change or clear the grade in Parent settings.
• “Where should I start?” game. A short word game a writer can play once. We keep which answers were right, the level it found, and the one sentence the writer wrote for Inky, exactly as written, so the parent can later compare it with newer writing. It is deleted with the writer or the account.
• Skills and level changes. From the lessons a writer finishes, we keep a short record for each writing skill (such as “uses commas in a list”): how many items were tried, how many were right first time, a score that leans on recent tries, and the current run of misses or right answers, so lessons can bring an easier item with a hint or offer a harder challenge. We also note each change to the writer’s level and why (the game, the grade, the parent, a move up the writer said yes to, or a move down after three tricky lessons). The parent can see and change the level, or lock it, in Parent settings. All of it is deleted with the writer or the account.
• Monthly growth check and the Progress page. From the month after the “Where should I start?” game, a writer can play a short check-in once a month. We keep which answers were right, the level it found, and the one sentence written for Inky, exactly as written, with what Inky said about it. Word Gym also notes the day a word counts as learned. The parent sees all of this, with the skills record, on the Progress page in Parent settings, and can print it. Nothing on it is shown to other writers. It is deleted with the writer or the account.
• Word Vault. For each word a writer has met in lessons, we keep the day it was first answered right first time, the day it was first used well in their own writing, and the day it was mastered. When Inky finds a lesson word used with the meaning the lesson teaches, we keep that first sentence, exactly as written, so the writer can see it on the word’s card. With each Inky check we also note which lesson words were used well. Only the writer and their own parent can see the Vault, and the parent sees its totals on the Progress page and in the weekly report. It is deleted with the writer or the account.
• Word Boss. At the end of each unit a writer can fight the Word Boss, a short test of the unit’s words. For each finished attempt we keep the day, how many answers were right and whether it passed. Its one written sentence is checked by Inky like any lesson sentence, and is kept only as described for the Word Vault above. It is deleted with the writer or the account.
• Word Roots. After lesson 2 of each unit a writer can play Word Roots, which teaches word parts like un- and -ful. For each finished lesson we keep the day and how many answers were right. Its one written sentence is checked by Inky like any lesson sentence and kept only as described for the Word Vault above. It is deleted with the writer or the account.
• Story Time. After lesson 4 of each unit a writer can read a short story and answer a few questions about it. Nothing is written. For each story we keep the day, how many answers were right and how long it took, so we only pay XP for a real read. It is deleted with the writer or the account.
• Daily Word Hunt. Each day a writer can find one new word. For each day we keep the word, whether their first guess at its meaning was right, when they finished and which Inky check their sentence passed, so we can count their Word Hunt streak. Its sentence is checked by Inky like any lesson sentence and kept only as described for the Word Vault above. It is deleted with the writer or the account.
• Word Duel. A writer can challenge an approved friend to answer the same ten word questions on the same day. For each duel we keep the two writers, the questions, when each started and finished and each score. Each writer sees the other’s score only after both have played, and there is no chat. Either writer’s grown-up can see the duel. It is deleted with either writer or account.
• Monthly writing events. When a writer enters a month’s writing event, we keep the story’s title and sentences, exactly as written, the writer’s level, and the score: how many sentences Inky read, how many it called great on the first try, and whether that beat the writer’s own recent writing. Entries are family-private like the Story Book; they are never shown to other writers or ranked against anyone. It is deleted with the writer or the account.
• Friend Quests. When two approved friends team up for a week, we keep which two writers teamed up, which week, the goal, and the prize they won. Progress is counted from the lessons each writer finished; the friend sees only the count (for example “3 lessons”), never the writing. There is no chat or free text between writers. A parent can switch friends off at any time, and it is deleted with the writer or the account.
• Avatar, collectables and Ink Drops. The avatar a writer builds in Avatar Studio from parts we draw (never a photo) and the day it was last saved, the Ink Drops they earn, the collectables they buy with them and when. If a writer swaps a collectable with an approved friend, we keep who offered what, the answer and the day, so swaps can be limited each day and undone.
• Reactions and notices. When a friend reacts to a shared card with one of our fixed reactions, we keep which reaction and when. The bell in the app keeps notices for the writer, such as a friend request or a finished duel. They hold only writer names and ids, never free text.
• Country. At sign-up we look up the country from the internet address (we don’t keep the address itself) and save it with the parent account, so we can show prices in the right currency and open Inkido country by country. We also note the currency of any Pro payment.
• Deleted writers. When a parent deletes one writer, we note only that the family deleted a writer and when, for 30 days, so a writer added in their place doesn’t get the new-writer gifts (the taster XP and chest Ink Drops) a second time. Nothing about the deleted writer is kept, and deleting the whole account leaves no note.
• Consent and visits. Which version of our sign-up notice you agreed to, when, and how (by confirming your email, or by paying for Pro), and when we sent the email confirming it. We also note the day the family last opened Inkido, so accounts nobody uses can be deleted.
• Subscription status. Whether you’re on Free or Pro, your plan and renewal date. Card details go straight to Stripe and never reach us.

What writers type

When a writer asks Inky for feedback on a sentence, that sentence is sent to Anthropic, the company that makes the Claude AI model, to write the feedback. We send the sentence and the exercise only, with no name or account details. Lesson sentences aren’t saved in our database, except one best sentence per writer per week for the weekly report and the first sentence that uses each lesson word well for the Word Vault, as described above. Story Challenge sentences are saved only once the writer finishes the story and puts it in their Story Book, as described above. Stories go to Anthropic only for Inky’s checks. For each check we keep what Inky said (for example “great” or “fix it first”) and a fingerprint of the sentence: scrambled numbers made from its words that can’t be turned back into the sentence. They let us count Inky’s bonus points fairly and notice a sentence that was copied or reused. These records are deleted after 60 days, or with the account. So the same words are never sent to Anthropic twice, we also keep Inky’s feedback on a sentence for 30 days under a scrambled key made from the sentence. It isn’t linked to any writer or account, though the feedback may quote a word or two of the sentence. Spelling and word checks done by Inky’s Notebook (our own word list) happen in the app and on our server, and nothing is sent to anyone for them.

Who helps us run Inkido

We share data only with the companies below, and only what each one needs to run Inkido for you. We can’t run Inkido without them.

• Supabase stores accounts, progress, stories and friends, so a writer’s work is saved between visits.
• Vercel hosts the website and runs our server code. Like any web host, it sees internet addresses when pages load and keeps them briefly in its logs.
• Anthropic writes Inky’s feedback on sentences. It gets the sentence and the exercise, never a name or account details, and doesn’t use them to train its AI models.
• Resend delivers our emails to parents, like sign-up links, friend requests waiting for your yes and the weekly report. It gets the parent’s email address and the email itself, which for the weekly report includes the writer’s first name, their week in numbers and their best sentence. Children never get email.
• Stripe and Link handle payments and subscriptions. Link, a Stripe company, is the reseller that sells Pro. They get the parent’s email and payment details, never anything about the writer.

Where data is stored

Inkido’s database is in the United States, in Supabase’s North Virginia region (us-east-1). Our other providers may also store or process data in the United States or other countries. Each one only gets what it needs for its job.

How long we keep children’s data

If we keep database backups, deleted data drops out of them within 30 days.

Stripe keeps payment records for as long as tax and finance laws require. Those records are about the parent, not the writer.

Cookies and browser storage

We use sign-in cookies so you stay signed in, and the app saves lesson progress in the browser so it works on a slow connection. We don’t use advertising or tracking cookies, analytics tools or any other trackers.

What we never do

• Sell data or show ads.
• Let writers message each other or share anything other than their writer name and animal.
• Let a child approve a friend: that needs the parent’s password.

Your choices

You can see and change what Inkido keeps from the app’s Profile and Parent settings. Delete account in Profile permanently removes the parent account, the writer, their progress, stories, writer name and every friendship, and cancels any subscription straight away. To ask a question, get a copy of your data or make a complaint, email privacy@inkido.ca. We answer within 30 days.

For parents in the United States

Inkido is made for children under 13, so we follow the US Children’s Online Privacy Protection Act (COPPA). Only a parent or guardian can make an account, and they agree to Inkido collecting their child’s information when they add a writer.

How you give consent: before signing up you see what we collect and who gets it, tick the consent box, and confirm your email. A day later we email you again to confirm what you agreed to, with a link to delete the account straight away if it wasn’t you. Paying for Pro also counts as consent.

• What we collect from children: the first name or nickname the parent types, what the writer writes in lessons and stories, and their lesson progress, all described under “What we keep” above. We don’t collect a child’s email, photo, full name, school, location or contact details, and children can’t share personal details with other writers.
• Who gets it: only the companies listed under “Who helps us run Inkido”, for the reasons given there. They are needed to run Inkido, and we don’t give children’s data to anyone else or use it for ads.
• Review it: sign in and open Parent settings to see your child’s progress, Progress page, Story Book and friends, or email us for a full copy.
• Delete it: Delete account in Profile removes the account and every writer’s data from our database straight away. To delete just one writer, email us and we’ll do it within 30 days.
• Stop collection: deleting the account, or asking us to delete a writer, stops all collection. You can also turn off friends, leagues, sharing and the weekly report in Parent settings at any time.

To ask about your child’s data, email privacy@inkido.ca.
