This policy explains what the Hindsight app ("Hindsight", "we") collects, why, who it is shared with, and how you can delete it. Hindsight is operated by Tom Plaes, 66 Rue Emile Deroover, 1081 Brussels, Belgium. Contact: plaes.dev@gmail.com.
Your first name, the year and voice you picked, your onboarding answers, your conversations with future you, a copy of the short memory note future you keeps about you, intentions, check-ins and settings. This stays on your device and is removed when you use "Delete all my data" or delete the app.
| Data | Why | Kept |
|---|---|---|
| A random anonymous user ID created when you first use the app | To apply fair-use limits and keep the service running | As long as the app is in use |
| Your message, recent turns of the conversation (at most 30), your first name, chosen year, voice and memory note | To generate future you's reply, daily letter or path entry | Not stored by us. Processed and passed to the AI provider, then discarded |
| Voice recordings during a voice call | To turn your speech into text and future you's reply into speech | Not stored by us |
| Daily usage counters (number of requests, seconds of talk time and voice) | To apply your plan's daily time and fair-use limits | 30 days |
| The memory note: a short summary (at most about 300 words) of what you shared, written by the AI, for example your job or a goal you mentioned | So future you remembers you in every conversation | Until you erase it (Profile → What future you remembers) or delete your data |
| How many messages of your free first conversation you used | To give each person one free conversation | As long as the app is in use |
| Your current plan (free or Plus), read from RevenueCat | To give you the time and features of your plan | As long as the app is in use |
| A one-way hash of your IP address when your anonymous ID is first used | To limit how many free accounts one network can create per day (abuse prevention). The hash cannot be turned back into your IP address | 30 days |
| Usage events: screens opened, steps completed (onboarding, purchase, data deletion), counts, error types. Never your messages, name or answers | To understand which parts of the app work and fix what doesn't | Up to 12 months |
| Crash reports: the error, device model and OS version, app version. No messages, no IP address | To find and fix crashes | 90 days |
| Safety events: only a category (for example "crisis") and the action taken, never your message | To check that our safety features work | 90 days |
| A reply you report with a long press, including its text | To review it and improve safety. You choose to send it | Until reviewed, at most 12 months |
Hindsight does not use your camera and does not read your contacts.
These providers act on our instructions and are bound by contracts that protect your data. Transfers outside the European Economic Area rely on the European Commission's standard contractual clauses or an equivalent safeguard.
We process data to provide the service you ask for (performance of a contract), to keep it safe and prevent abuse (legitimate interest), and, for anything you choose to report, on the basis of your action. Conversations about your wellbeing can reveal sensitive information. You choose what to share, and you can delete it at any time.
You can access, correct or delete your data. Profile → Delete all my data removes it from your phone and deletes your anonymous ID on our server, with its memory note, usage counters, plan record, reported messages and safety events, and your RevenueCat customer record. Usage events and crash reports already sent are no longer linked to a new ID; to have them erased too, or for any other request, write to plaes.dev@gmail.com. You can also complain to your data protection authority (in Belgium, the Autorité de protection des données / Gegevensbeschermingsautoriteit).
Hindsight is for people 17 and older. We don't knowingly collect data from younger people. If you think a minor is using the app, contact us and we will delete the related data.
If this policy changes, we update the date above and, for important changes, tell you in the app.
