Privacy Policy

1. Who we are

ThinkProv ("we", "us") is an app for training how you think and speak under pressure. It is operated by Indrasyah Putera, trading as ThinkProv, an individual developer in Singapore, who is responsible for your personal data under Singapore's Personal Data Protection Act 2012 (PDPA).

For anything about your data, including to reach our data protection contact, email support@thinkprov.com.

This policy covers the ThinkProv mobile app, app.thinkprov.com and thinkprov.com.

2. What we collect

Your account

• Your email address and a password (held by our sign-in provider; we never see it in plain text).
• If you sign in with Google: the name and email address on your Google account.
• If you sign in with Apple: the name and email address Apple shares with us. If you choose to hide your email, Apple gives us a private relay address that forwards to you instead.
• The first name you give us, which the coach uses to talk to you.

Your answers when you join

• The areas you want to talk about (for example technology, or arts and culture), what happens to you under pressure, how often speaking matters to you, how you try to change someone's mind, and any upcoming event you are preparing for, with its date.
• Your timezone, read from your phone, so your day and your streak start at midnight where you are.
• Whether you want a daily reminder, and when.

Your practice

• Recordings. When you do a rep, your voice is recorded and sent to an AI service to be transcribed and scored (section 4). Recordings are not kept on our servers; see section 6 for the two short exceptions.
• Video. If you film a Cold Stage rep, the video stays on your phone. Only its sound is sent for analysis.
• Transcripts, scores and AI feedback for every rep, and the timings of your words.
• What we build from your reps: your thinking map (the ideas you have used and how they connect), your daily programs, XP, streak, course progress, the topics you have been given, practice topics suggested from what you have said, and your Mental Models progress and reflections.
• Your feedback on reports: the thumbs, reasons and notes you give, stored with the topic and the part of the report you rated.

Challenges you send a friend

• When you challenge a friend, we keep the prompt, your score, your first name and your transcript for that rep. Your friend sees your first name, the prompt and, after they play, your score (section 5). The transcript is used only to write their coaching line and is never shown to them. If your friend signs up to see their result, you see their first name and their score (never their answer or analysis); they are told this before they sign up.
• A friend's answer waits in storage, unscored, for up to 7 days. It is only sent to AI to be scored if they sign up, agree to AI processing and ask for their result; otherwise it is deleted. We note which account's challenge a new account signed up through. We also keep a one-way scrambled (hashed) form of their internet address, only to stop the link being abused.

Technical data

• A record of each AI request made for your account (which service, its size and cost), to run and budget the service.
• If you turn on reminders, a notification token for your phone may be stored.
• Sign-in session data on your phone and, on the web, the cookies or local storage that keep you signed in.

We do not collect your location, your contacts, advertising identifiers or your voice as a biometric identifier. The app contains no advertising or third-party analytics tools.

3. How we use it

• To run the training: transcribe and score your reps, write your feedback, build your daily program and pick your topics, including topics suggested from what you said in your recent reps.
• To show your progress over time.
• To improve the quality of the coaching, including by reading the feedback you give on reports.
• To keep the service secure, stop abuse and keep costs in check.
• To answer you when you contact us.

We do not sell your personal data, we do not use it for advertising, and we do not create voiceprints or try to identify you from your voice.

4. AI processing, and your consent

ThinkProv's coaching is written by AI. Before your first rep, the app asks you to agree to your recordings and answers being processed by the AI services below. You can read this again, and withdraw, at any time in the app under Settings, AI and your voice. If you withdraw, new reps are no longer analysed (our servers refuse them too) and your transcripts are left out of the daily topic suggestions; what you already have stays until you delete it.

• Google (Gemini, through Google Cloud Vertex AI). Hears the audio of your Cold Stage reps, your baseline and your Framework drill takes, with the topic and your first name, and returns a transcript, scores and feedback. May also score drill transcripts, and writes drill prompts, reads your Mental Models reflections and writes a challenge's coaching line. Under Google Cloud's terms, this data is not used to train Google's models.
• Anthropic (Claude). May score and coach drill transcripts (we choose which of Gemini and Claude scores drills), and handles some other coaching requests. Once a day, it also reads the transcripts of that day's reps to suggest practice topics for you; it is told to leave out the names of people you know. Anthropic does not train its models on this data by default.
• Deepgram. Turns the audio of drill reps, Mental Models reflections and a challenge answer into text. Deepgram may keep samples of this audio to improve its own speech models, under its terms.

AI feedback can be wrong. Every report is labelled as AI-generated, and you can rate each part of it or report anything offensive or harmful from the report itself.

5. Who else sees your data

Service providers

Besides the AI services in section 4, these providers run parts of ThinkProv for us. They may only use your data to provide their service to us.

• Supabase: our database, sign-in and file storage.
• Vercel: hosts our servers and the website.
• Google: sign-in, if you choose Sign in with Google.
• Apple: sign-in, if you choose Sign in with Apple.
• Apple and Google: deliver the app to your phone.

Other people

Your reps, transcripts, scores and feedback are private to you. The one exception is a challenge you choose to send: your friend sees your first name, the prompt and your score, and if you turn it on, how your map for that rep looks and how large your whole map is (as two numbers, not its words). Your friend never hears your recording or sees your transcript. It works the other way too: if you play a friend's challenge and sign up to see your result, they see your first name and your score, and nothing else of yours. There are no public profiles or leaderboards.

The law

We may disclose data if the law requires it, or to protect the rights, safety or property of our users or others.

If ThinkProv changes hands

ThinkProv may be transferred to a company set up to run it, or to a new owner as part of a merger, acquisition or sale of the business. Your account and data would move to that successor, which would be bound by this policy. We will tell you in the app before the transfer takes effect.

6. How long we keep it

• Recordings on our servers: your three baseline reps wait in storage only until they are scored, then are deleted; any left behind by a failed attempt are deleted within a day. A friend's challenge answer is deleted once it is scored, or after 7 days if it never is. All other recordings are sent for analysis and never stored by us.
• Recordings on your phone: kept for the time you choose in Settings (1 to 30 days), then deleted.
• Transcripts, scores, feedback and progress: until you start over or delete your account.
• Topics suggested for you: a suggestion you don't practise is deleted after 30 days; one you practise stays with that rep. All are cleared if you start over or delete your account.
• Challenge links: expire after 12 hours or 10 plays; challenges are removed when you delete your account.
• Records of AI requests: kept for accounting; when you delete your account they are no longer linked to you.
• Your feedback on reports: kept if you start over (it is feedback to us, not your progress), and deleted with your account.

7. Where your data is processed

Our providers run servers outside Singapore, including in the United States. When your data is transferred overseas, we rely on their contractual terms to protect it to a standard comparable to the PDPA.

8. Your choices and rights

Most of this you can do yourself, in the app, under Settings:

• Download my data. In Privacy and data: a copy of your transcripts, scores, feedback and settings, as a file.
• Correct your details. Change your areas, thinking style, timezone and reminders in Settings.
• Start over. In Account: clear your scores and progress and take a new baseline, keeping your account.
• Delete account. In Account: deletes your account and everything we hold about you, straight away. You can also ask by email or at app.thinkprov.com/delete-account; we complete an emailed request within 30 days.
• Withdraw AI consent. In AI and your voice. You can also choose there how long recordings stay on your phone.
• Permissions. The microphone, camera and notifications can be changed in your phone's settings.

You can also email support@thinkprov.com to ask what we hold about you, how it has been used, or to correct it. We will reply within 30 days, or tell you if we need longer.

9. Security

Data travels encrypted. Our database only lets each account read and write its own rows, and the keys to the AI services are kept on our servers, never in the app. No system is perfectly secure; if a data breach is likely to cause you significant harm, we will tell you and Singapore's Personal Data Protection Commission as the PDPA requires.

10. Age

ThinkProv is for people aged 13 and over. If you are under 18, please use it with a parent or guardian's knowledge. We do not knowingly collect data from children under 13; if you believe a child under 13 has an account, email support@thinkprov.com and we will delete it.

11. Changes to this policy

If we change this policy, we will update the date at the top. If a change affects how your data is used in a significant way, we will tell you in the app before it takes effect.

12. Contact

Questions, requests or complaints: support@thinkprov.com. If you are not satisfied with our answer, you can contact Singapore's Personal Data Protection Commission at pdpc.gov.sg.
