Privacy Policy

Effective 4 October 2026 · Comigo for iOS and the comigo.net website

Comigo is made by an independent developer. The app is designed to work without user accounts, without third-party advertising, and without cross-app tracking. This page explains the small amount of data that is processed to make the app's features work, and nothing here will try to surprise you.

What Comigo does not do

• No user accounts — we don't know who you are.
• No third-party advertising is displayed in Comigo, and we don't use advertising networks to track you across other apps or websites.
• No advertising identifier.
• No sale or sharing of personal data with data brokers — ever.

The comigo.net website

The website doesn't use cookies, doesn't store or read anything on your device, and loads no analytics or advertising scripts.

To learn whether our adverts work, our server keeps simple counts: how often the reading-practice pages are viewed, and how often "Get the app" buttons are tapped and on which page. Each count records only the page or button, the time, and — if you arrived from one of our adverts — the campaign tags in that advert's link (such as "google"), which are the same for everyone who taps it. It does not record your IP address, browser details or any identifier, and it makes no attempt to recognise you or connect your visits. These counts contain no personal data; they're sent to PostHog, our analytics provider, and stored in the EU.

If you arrived from one of our adverts, the App Store link includes a campaign code so that Apple can tell us how many downloads that advert led to. We only ever receive totals from Apple, and Apple handles the App Store visit under its own privacy policy.

Like any website, our hosting provider (Fly.io) processes your IP address to deliver pages to you.

Your voice, during speaking practice

When you use a speaking exercise, the app records your answer and sends that audio clip over an encrypted connection to our server, which forwards it to OpenAI's transcription service to turn your speech into text so the app can assess your Spanish. The audio is processed and discarded: our server holds it only in memory while the request is handled and never stores it, OpenAI's transcription service does not retain it, and OpenAI does not use data submitted through its API to train its models. The recording is not linked to any identifier, and the temporary copy on your device is deleted after processing.

Microphone access is optional — if you decline it or switch speaking exercises off, everything else in Comigo (reading, listening, silent practice) works normally.

Words and sentences you ask about

When you tap a word or sentence for an explanation, the text of that sentence is sent to our server and on to OpenAI to generate the explanation. This text comes from the comics themselves, not from anything you've written.

Anonymous usage counts

The app keeps simple counts of actions — a page read, a practice finished, a paywall shown, a translation revealed — so we can see which comics and features get used. These counts are on by default and you can switch them off at any time in Settings → Privacy → Anonymous usage counts; switching them off also discards any counts not yet sent, and every part of Comigo works the same either way.

Each count is a named action (such as "comic page viewed" or "practice completed") with the comic or collection, the page number, the practice mode, whether you're on the free plan, a trial or a subscription, and the app version. It carries no identifier of any kind: no account, device, install, session or advertising identifier, no random code, no name, email address or Apple ID, no location, and never your voice, your answers, anything you type or the text of the comics. The app sends these counts in small batches to our server, which passes them to PostHog, our analytics provider in the EU, under a single fixed label for the whole app. Our telemetry service does not store, forward, hash or derive a location from the IP address on that connection, and does not use it as an identifier. The result is a tally of what was done, not who did it: the telemetry is designed so that the counts are not linked to you, cannot be combined into an individual usage profile, and don't measure or recognise individual users. They are used only to understand how Comigo is used and to improve it, never for advertising.

Optional individual usage analytics — only if you allow it

Separately from the anonymous counts above, when you first use Comigo the app asks whether you'd like to share usage statistics. No optional individual usage analytics are collected unless you choose Allow analytics; if you choose No thanks, the app never starts its analytics service and nothing is sent. Every part of Comigo works the same either way. You can change your answer at any time in Settings → Privacy → Share usage analytics.

If you allow it, the app sends usage statistics to PostHog, our analytics provider, which stores them in the EU. Each statistic is a named action (such as "comic page viewed" or "audio played") with details like the comic, the page number, the practice mode, whether you're on the free plan, a trial or a subscription, the Spanish level you chose in the app, your app version, your iPhone or iPad's operating system version and whether it's a phone or a tablet. Unlike the anonymous counts, these statistics are linked together, so they show how one person's reading and practice unfold over time — which is why they need your permission.

These statistics are linked to a random analytics identifier created on your device, not to your name, email address, Apple ID or any advertising identifier. They never include your voice, your spoken or written answers, anything you type, or the text of the comics. Your IP address is not stored and is not used to work out your location. The statistics are used only to understand how Comigo is used and to improve it — never for advertising, never combined with data from other companies, and never sold. We rely on your consent for this, and you can withdraw it at any time in Settings.

Subscriptions. If you've allowed analytics and you start a trial or subscription, the app attaches a random purchase code to it. Apple tells our server when that subscription renews, converts from a trial, is cancelled, expires or is refunded, and the code lets us count those events under the same random identifier. Apple does not share your identity with us, and we never learn your Apple ID, name or payment details. If you turn analytics off, the link between the purchase code and your identifier is deleted from our server and no further subscription statistics are recorded for you.

How long it's kept. PostHog keeps analytics data, including anonymous usage counts and optional individual usage statistics, for up to 7 years under our current plan. We review at least once a year how much of this data we still need and reduce or delete analytics data once it is no longer needed to understand and improve Comigo. Anonymous usage counts contain no user, device, installation or session identifier. Optional individual usage statistics are linked only to a random analytics identifier and not to your identity; turning optional analytics off stops any further collection straight away.

The record on our own server that links a purchase code to your random identifier is kept only while analytics is on. It is deleted immediately if you turn analytics off. Otherwise it is kept while your subscription is active, because each renewal or other change Apple reports needs it, and it is deleted automatically 12 months after the last such subscription activity. Our records of the subscription notifications themselves are deleted automatically after 12 months.

What stays on your device

Your reading progress, practice scores, vocabulary, notebook entries, the Spanish level you chose and downloaded comics are stored only on your device (and in your own device backups). They are never uploaded to us, except that the Spanish level is included in usage statistics if you've allowed them.

If you turn on reading reminders, they are scheduled by iOS on your device. We don't record when you use the app to send them, and nothing about them is sent to us.

Server logs

Like practically every internet service, our servers keep short-lived technical logs of requests (IP address, endpoint, timestamp) for reliability and abuse prevention. They are not used to profile you and are routinely discarded.

Service providers

• OpenAI — speech transcription and language explanations, as described above.
• Fly.io — hosts our server.
• Tigris — delivers comic downloads (content files only).
• PostHog — app usage analytics, only if you allow it, and the website's anonymous visit counts (EU data storage).
• Apple — processes App Store purchases and notifies our server of subscription changes, and reports download totals for our advert campaigns, as described above.

Each receives only what is needed to perform its function.

Children

Comigo is intended for adults and older teenagers. It does not ask for names, email addresses or any other information that identifies you, and does not knowingly collect personal information from children.

Changes

If this policy changes, the updated version will be published at this address with a new effective date.
