Privacy policy.

01Who we are

Vivink is a handwriting studio for notes and teaching that runs in your web browser. In this policy, “Vivink”, “we” and “us” mean the team behind Vivink. You can reach us any time at hi@vivink.com.

02What stays on your device

Everything you make in Vivink is saved in your browser, on your own device, the moment you write it:

• Notes and boards — your ink, slides, photos, videos and attached files.
• Recordings — saved as a video file on your device. Vivink does not upload them.
• Settings — your pens, paper, toolbar and theme choices.

Reading your handwriting happens on your device. Search and automatic titles read your writing with a reading engine that runs inside your browser. The engine is downloaded once from a public software library; your notes are never sent with it.

Slides from a PDF are made on your device too. The PDF reader is loaded from a public software library (cdn.jsdelivr.net); your file stays with you.

03Camera, microphone and screen

Vivink asks for your camera, microphone or screen only when you use something that needs them, and your browser always asks your permission first:

• A recording — they are used only for that recording, and the video is saved to your device.
• Your voice in a session — when you switch it on, your microphone goes live to the students who listen.
• Asking to speak — a student’s microphone is checked when they ask, and goes live only once their teacher allows them, until their turn ends.
• Showing a website — your browser asks which tab to share, and only what you pick is shared.

Vivink doesn’t record or keep this sound or video. The only recordings are the ones you make yourself, saved on your device. See Voice and websites in a session. You can turn any permission off at any time in your browser’s settings.

04Sync between your devices

When you use sync, your notes and their files are sent over an encrypted connection to the Vivink sync server, so your other devices can show the same notes. When you delete a note for good, it is removed from the server as well.

If you invite someone to teach with your notes, the server sends the notes you share to their devices in the same way — see People you invite.

05Live boards and sessions

When you share a board — on a class TV, or with a session link and its QR code — what you write goes live through the Vivink server to the people watching: your ink as you write it, your laser, the part of the page in view, and the note the board shows, with its pictures. They see only that note, never the rest of your notes, and they can’t write on it. Students who follow a session link don’t need an account.

For each board, the Vivink server keeps:

• Its settings — such as the student limit, whether it asks for names and your questions, whether students can ask to speak, and the session password.
• The session password — kept as you typed it, so you can read it out again. It’s a short code for one session, not an account password, so never use one you use anywhere else.
• Past sessions — when a session ends, the board’s name, when it ended, the most who watched at once and the session’s numbers, until you delete that session.
• Who runs it — the name students see on the board. When someone you invited runs a session on your notes, it’s their name, and the session is marked “Run by” them in your Past sessions.

06Voice and websites in a session

Sound and live video in a session go through Cloudflare Realtime, a service that passes them on to everyone listening or watching. They don’t pass through the Vivink server, which only helps the devices connect, and Vivink doesn’t record or keep them. Each device connects to Cloudflare to send or receive them, so Cloudflare receives its IP address, as with any connection, under Cloudflare’s privacy policy.

• Your voice — when you switch it on for a board, your microphone goes live to those who listen. On a session link with a password, only those who typed it can hear you.
• Students who ask to speak — only on a session link where you switch it on. A student’s microphone goes live only after you allow them, and only until their turn ends: to you alone, or to everyone if you choose “Everyone”. Classmates see the speaker’s name only while everyone hears them, and nothing of it is kept in Past sessions.
• Showing a website — the tab you pick is captured by your own browser and sent as live video, with the tab’s sound if you share it, to your students and your class TV. You sign in to the website in its own tab, so Vivink never sees your passwords for it. Everyone watching sees what is in that tab, so close anything private first.

Vivink keeps nothing of a website you show. While it shows, the Vivink server holds only its name, the address you typed and your ink over it, so a student who joins late sees them too; they go when you stop. If you put a picture of it on your page (“Put a picture on the page” or “Keep the last picture”), that picture, with your ink, becomes part of your note like any photo. Your own recordings film the website too, and are saved on your device.

07Your students’ details

A session link can ask students for their name and up to five questions of your own — like a roll number, a section, or a phone number or email. It’s off unless you switch it on, and a class TV is never asked.

You decide what to ask, and why. For these details, you (or your school) choose what is collected, and Vivink keeps it for you and shows it only to you. So:

• Ask only for what you need. A name and a roll number are often enough. Never ask for passwords, bank details or ID numbers.
• Have a reason, and say it. You’re responsible for having a good reason to collect what you ask, and for telling your students — or their parents — what you ask for and why.

What Vivink keeps for you:

• The attendance list — each student’s name and answers, when they joined and left, each visit and the minutes they watched, kept on the Vivink server with that session so you see it in Who’s here and Past sessions on any of your devices.
• The session’s numbers — worked out from the list: who joined late, left early or came back, and the average time watched.
• Only you see it. It opens only for your signed-in account — and, for a session someone you invited runs on your notes, for them too, while they can teach with your notes. Vivink never sends a student’s name or answers to other students and never writes them to its logs, and a question about a phone number or an email tells students “Only your teacher sees this.”
• Kept until you delete the session. Every session stays in Past sessions until you delete it there, and its list goes with it.
• Save the list makes a spreadsheet file (CSV) on your device, with the names, answers and times. Once saved, that file is yours to look after.

On a student’s phone, Vivink remembers, for each session link, a random id for that phone, the name and answers typed there and a key for the session password (not the password itself), so a reload doesn’t ask again. Clearing the browser’s site data removes them — see our Cookie policy.

08People you invite

From Invite people at the foot of your notes list, you can invite another person to teach with your notes. You choose what they see — all your notes, or only the folders and notes you pick — and what they can do: Can teach or Can view. You can change either, or remove them, at any time.

For each invite, the Vivink server keeps:

• Who it’s for — the email address you type, and their name once they have an account.
• What you chose — what they see, what they can do, and the short message you add, if any.
• Where it stands — invited, accepted or declined, and when it was sent, answered and last changed.
• The link — only a fingerprint of its code, which can’t be turned back into the link. It works for 7 days, once, and only for the email address it was sent to.

The emails. Vivink emails the person you invite: the invite, with your name and email address, your message, the names of the notes you share and what they can do — and a reminder with a new link if you send it again. When they accept, you get an email with their name and email address. When you change what they see or can do, or remove them, they get an email saying so, unless you switch that off in People. Replies to the emails they get go to you, not to Vivink. Whoever opens an invite’s link sees what its email says, but only that email address can accept it.

What each of you sees. They see your name and email address. You see theirs in People, and whether they accepted or declined.

• Only what you share — the server sends their devices only the notes and folders you chose, never the rest of your notes, not even their names. A note you move to Recently deleted is no longer shared.
• A copy on their device — the notes you share are kept in their browser, apart from their own notes, and sync while they have access. A note you stop sharing leaves their device.
• Can teach lets them write on those notes (it saves to your notes), show them on a TV, run Live sessions, show a website and record to their own device. Can view only lets them read the notes on their own screen. Neither can make, delete, rename, move, share or export your notes.
• Sessions they run on your notes are yours — the link, the attendance list and the Past sessions record belong to your account, marked “Run by” with their name, and students see their name on the board. While they can teach with your notes, they see the sessions they ran there, with the attendance, and can save the list. Only you can delete those sessions.
• When you remove them, their access ends at once, and so does any session they are running on your notes. Vivink deletes the copy of your notes on each of their devices that has Vivink open and online at that moment; a device that doesn’t may keep the copy it had, but gets nothing more of your notes. Recordings and lists they saved on their own device stay with them.

If someone invited you, the email address they typed and the invite are kept as above, and they see whether you accepted or declined. You can make your Vivink account from the link — the link confirms your email address, so no other email is needed, and you don’t need a plan — or log in, then accept or decline. Not expecting it? You can ignore it: the link stops working after 7 days. To have an invite taken off the list, ask the person who sent it, or write to hi@vivink.com.

09Your account and payments

To buy a plan, or to accept an invite to someone’s notes, you create an account. We keep:

• With email: your name, email address and password. Passwords are stored only in a scrambled (hashed) form that can’t be read back.
• With Google: the name, email address and profile picture Google shares with us when you choose “Continue with Google”.
• Your plan: which plan you bought, when, the amount and whether the payment went through.

Payments are handled by Razorpay. You enter your card, UPI or bank details on Razorpay’s secure checkout, under Razorpay’s privacy policy. We never see or store them.

We use your email to send a link that confirms your address, a link to set a new password when you ask for one, receipts and important messages about your account — and, if you invite people or are invited, the emails described in People you invite. We don’t send marketing emails unless you ask for them.

Our emails come from noreply@vivink.com and are delivered by Resend, an email service, which receives each email’s address, subject and contents to deliver it, under Resend’s privacy policy.

10Network addresses and limits

Like any website, the Vivink server sees the IP address of each device that connects to it. We use it only to keep Vivink working, safe and fair:

• Limits on tries. The server counts requests from each address for a short time, so nobody can guess a session password, sign in again and again, send invites again and again, or overload a session. Three wrong session passwords from one phone and address mean a minute’s wait. Because a school’s students often share one address, a session’s limits grow with how many are watching it.
• Kept in memory only. These counts live only in the server’s memory. They are never saved to its files, and never kept with your notes, attendance lists or Past sessions.
• A connection log. When a device opens the Vivink app, the server notes its address and the time in its log, which helps when a tablet can’t connect.

11This website

The Vivink app uses no analytics and no advertising. Our website uses one advertising tool — the Meta Pixel. A few things you should know:

• Meta Pixel — on our home, features and offer pages, and on the sign-up and log-in pages. It tells Meta (Facebook and Instagram) that a page was visited or that a plan was chosen, so we can measure our ads and show them to people likely to want Vivink. Meta receives your IP address, your browser and the page you’re on, sets a cookie (_fbp), and may connect this to a Meta account under Meta’s privacy policy. Your notes are never sent. You can control the ads you see in your Meta ad settings, or block third-party cookies in your browser.
• Fonts are loaded from Google Fonts, so Google receives your IP address, as with any web request.
• Prices in your currency: the page guesses your country from your device’s time zone — on your device, nothing is sent — and fetches today’s exchange rates from a public rate service. The rate is remembered in your browser for one day.

See our Cookie policy for everything stored in your browser.

12What we never do

• Sell, rent or trade your personal data.
• Show ads inside Vivink, or share your notes with anyone you didn’t choose.
• Read your notes to profile you, or use them to train AI models.

13How long we keep things

Notes on your device stay until you delete them. Deleted notes wait in Recently deleted for 30 days, then are removed for good. Account details are kept while your account is open; payment records are kept as long as the law requires.

A session’s list and numbers stay in Past sessions until you delete that session, and its password until you turn it off, change it or delete the session. Hands raised to speak and a website you show are held only in the server’s memory, and only while the session is live.

An invite stays on the Vivink server until you cancel it, remove the person, or take a declined or expired one off your list in People. Then their email address, name and your choices are deleted; only the fingerprint of its link is kept, for 90 days and with no email address or name, so the link can say why it no longer works. Sessions they ran on your notes stay in your Past sessions, marked with their name, until you delete them.

14Your choices and rights

You can export any note as a PDF or an image, back up all your notes to one file, and delete notes whenever you like. You can also ask us to show you, correct or delete the personal data we hold about you, or to close your account — write to hi@vivink.com and we’ll help. Depending on where you live, laws such as India’s Digital Personal Data Protection Act, 2023 or the GDPR in Europe give you these rights too.

In People, you see everyone you invited, and can change what they see or can do, or remove them, at any time.

If you joined a teacher’s session, your name and answers are in that session’s attendance list. Ask your teacher if you’d like to see them or have them removed: teachers decide what is kept, and the session can be deleted in Past sessions. You can also write to hi@vivink.com.

15Children

Vivink is used in classrooms. If you are under 18, please use Vivink with the permission of a parent, guardian or your school.

Students who follow a session link don’t make an account. If you teach children, ask them for as little as you can — a first name is often enough — and follow your school’s rules and the law where you teach, including when a parent’s permission is needed.

16Keeping your data safe

Vivink is served over an encrypted connection (HTTPS), passwords are stored hashed, and payments go through Razorpay. Your notes are only as safe as your device, so keep it locked and back up your notes from time to time.

Attendance lists and your students’ answers open only for your signed-in account, and for someone you invited, for the sessions they ran on your notes, while they can teach with them. Invite links are random, kept only as fingerprints, and work for 7 days, only for the email address they were sent to. A session link can also ask for a password, and wrong tries are limited — see Network addresses and limits.

17Changes to this policy

If we change this policy, we’ll update the date at the top of this page, and tell you in Vivink or by email when a change matters.
