SpeakZilla Privacy Policy

Effective date: 19 August 2026

Last updated: 1 October 2026

SpeakZilla ("SpeakZilla", "we", "us") is a pronunciation-practice app

operated by Andrew Kim, Ontario, Canada. This policy explains

what personal data we collect, why, who we share it with, and the choices

and rights you have.

If you have questions, contact us at support@speakzilla.app.

1. Who this policy covers

This policy applies to everyone who creates an account or uses SpeakZilla

on the web or in our mobile apps.

2. Information we collect

a) Account information

• Your email address and a password (passwords are stored only in hashed

form by our authentication provider — we never see or store your plain

password).

• A display name, which by default is derived from your email address.
• If you sign in with Apple or Google instead of a password: the email address that provider gives us and, where the provider shares them, your name and profile picture, which we show on your Profile screen. We receive nothing else from your Apple or Google account, and we never see that account's password.
• Two settings, so the app behaves correctly for you: your time zone (so that daily limits, streaks and missions turn over at your own midnight) and your chosen app language (so that account email reaches you in it).

b) Learning activity and progress

• Your lesson progress, scores, accuracy history, streaks, points, tokens,

daily missions, and which lessons you've completed.

c) Your speech, and the transcript of it *(the most important category —

see Section 3)*

• When you practise, your speech is captured and streamed for scoring, and a

text transcript of what you said is generated.

• We store the transcript and the resulting pronunciation scores (overall and

per word/sound). On the mobile app we do not store the audio itself —

see Section 3.

d) Sentences you write yourself *(the "Sentences" feature — see Section 3a)*

• The text of each sentence you type or paste to practise, when you created it, which voice read it to you, and your scores for it.
• This is your own text, so it contains whatever you put in it. Please do not include sensitive information (such as health details, passwords, or other people's private information).
• If you ask to be told when a paid plan becomes available, we record that you asked, and when.

e) Information collected automatically

• Basic technical data needed to run and secure the service (for example

IP address, device/browser type, and timestamps), collected by our

hosting and backend providers through standard server logs.

We do not collect payment information, precise location, your contacts, or

anything from an Apple or Google account beyond what is listed in (a).

3. Voice data — how it works

Because SpeakZilla scores pronunciation, using it necessarily involves

recording your voice. Specifically:

• Capture: while you practise, the app captures your speech as you read

the sentence aloud.

• Processing: your speech is streamed to Microsoft Azure AI Speech,

which transcribes it and assesses pronunciation accuracy in real time and

returns the scores. See Microsoft's terms for how they handle audio.

• Storage: the mobile app does not keep your recordings. What we store

is the resulting transcript and the scores (overall, per word, and per

sound), so you can review progress and so features like spaced repetition

can resurface sounds you find difficult. Where a recording is stored (for

example if you use SpeakZilla on the web), it is deleted automatically after

90 days.

You control this data — see Your rights (Section 7). If you do not want

your voice recorded, you should not use the practice features, as they

cannot function without it.

3a. Your own sentences — how it works

The "Sentences" feature lets you practise a sentence you write yourself. Specifically:

• Storage: the sentence and your scores for it are stored with your account, so you can practise it again. You can delete any sentence at any time in the app; it is then removed from our database.
• The voice that reads it to you: to let you hear the sentence, its text is sent to a speech-generation service. Where the sentence is read in your coach's voice, the text is sent to ElevenLabs; otherwise it is sent to Microsoft Azure AI Speech. Only the text of the sentence is sent — not your name, email address or account identifier.
• What ElevenLabs keeps: ElevenLabs records each request in our account with them. We delete that record as soon as the audio has been generated, and we have opted out of ElevenLabs using it to train their models. ElevenLabs states that deleted items may remain in its backups for up to 30 days.
• The audio: the generated audio is saved on your own device only, so the sentence can be replayed. We do not store it on our servers.
• Scoring: when you say the sentence, your speech is scored exactly as described in Section 3, with your sentence as the reference text.

4. How we use your information

We use the data above to:

• provide the core service — recognise your speech and score pronunciation;
• track and show your progress, streaks, and achievements;
• personalise practice (e.g. resurfacing sounds you struggle with);
• operate, secure, debug, and improve the app;
• communicate with you about your account (e.g. password resets);
• tell you when a paid plan becomes available, if you asked us to.

We do not sell your personal data, and we do not use your voice

recordings to build or train speech models.

5. Who we share data with (service providers)

We share data with the following processors solely to run SpeakZilla. Each

processes data on our behalf under their own terms and security controls:

Please review each provider's own privacy documentation:

• Supabase: https://supabase.com/privacy
• Microsoft Azure: https://privacy.microsoft.com
• ElevenLabs: https://elevenlabs.io/privacy-policy
• Cloudflare: https://www.cloudflare.com/privacypolicy/
• Resend: https://resend.com/legal/privacy-policy
• Expo: https://expo.dev/privacy

Apple and Google act as sign-in providers if you choose them. They are not our

processors, and their own privacy policies govern your account with them.

We may also disclose data if required by law, to protect our rights, or as

part of a business transfer (e.g. merger or acquisition), in which case we

will notify you where required.

6. Data retention

We keep your account and progress data for as long as your account is active.

The mobile app does not store your voice recordings at all. Your speech is

streamed for scoring and discarded; only the transcript and the scores are

kept. Where a recording is stored — currently only if you practise on the web —

it is deleted automatically after 90 days.

Sentences you write yourself are kept until you delete them or your account. The copy of the text that ElevenLabs records when it generates the coach's voice is deleted by us immediately afterwards; ElevenLabs states that it may remain in its backups for up to 30 days. The generated audio exists only on your device and is removed when you delete the sentence or the app.

When you delete your account, we delete or anonymise your personal data within

30 days, except where we must retain some data to comply with legal

obligations.

7. Your rights and choices

Depending on where you live (e.g. under GDPR or CCPA/CPRA), you may have

the right to:

• access the personal data we hold about you;
• correct inaccurate data;
• delete your data ("right to be forgotten");
• export a copy of your data (portability);
• object to or restrict certain processing;
• withdraw consent where processing is based on consent.

To exercise any of these, use the in-app Delete account option in your profile, or email

us at support@speakzilla.app. We will respond within the timeframe required by

applicable law. You will not be discriminated against for exercising these

rights.

8. Data security

We use industry-standard measures to protect your data, including

encryption in transit, access controls that restrict each user's data to

that user (row-level security), and reputable infrastructure providers. No

method of transmission or storage is 100% secure, so we cannot guarantee

absolute security.

9. International data transfers

SpeakZilla is operated from Canada. Your account, progress and transcripts

are stored by Supabase in the United States. Your speech is processed by

Microsoft Azure AI Speech in Canada (the Canada Central region). The text of sentences you write yourself is sent to ElevenLabs in the United States when your coach's voice reads them. Microsoft,

ElevenLabs, Resend, Expo and Cloudflare are United States companies; Cloudflare serves the website from the

data centre nearest to you. Where required, we rely on appropriate safeguards

(such as Standard Contractual Clauses and each provider's data processing

agreement) for these transfers.

10. Children's privacy

SpeakZilla is not directed to children under 16, and we do not knowingly collect personal data from them.

If you believe a child has provided us data, contact us and we will delete

it.

11. Changes to this policy

We may update this policy from time to time. If we make material changes,

we will notify you (e.g. by email or an in-app notice) and update the

"Last updated" date above.
