Privacy Policy
Last updated: May 21, 2026
Your privacy matters. This Privacy Policy explains what we collect, why we collect it, and what we don’t collect when you use Memerio.
1. What We Collect
To make Memerio work, we process the following:
- Account identifier. When you sign in with Apple, we receive a stable but opaque user ID. We never see your Apple email if you choose to hide it.
- Voice recordings (temporarily). The audio of your spoken diary entries is captured on your device, transcribed locally by Apple’s Speech framework, and then deleted from the device shortly after transcription. We do not upload audio files to our servers.
- Diary content. The text of your transcribed entries, the AI-generated diary text, weekly and monthly summaries, and the illustrations and animations generated for those entries.
- Settings. Your selected writing style, language, AI model, emoji preference, and similar in-app choices.
- Diagnostics. Anonymous crash data and basic error logs sent by Apple’s system frameworks. We do not run our own analytics.
2. Where Your Content Lives
- On your device. Diary text, illustrations, and animations are cached locally so the app works offline.
- In your private cloud space. The same content is mirrored to Google Firebase (Cloud Firestore for text, Cloud Storage for images and videos). Each user has an isolated namespace; nobody else, including us in normal operation, can read your space.
3. Third-Party AI Providers
To produce diary prose, summaries, illustrations, and animations, parts of your text are sent to one or more of the following providers depending on your in-app selection and feature:
- Anthropic (Claude) — text generation. Privacy
- OpenAI (GPT and gpt-image) — text and image generation. Privacy
- DeepSeek — text generation. Privacy
- MiniMax (Hailuo) — image-to-video animation. Privacy
We send only the minimum content needed for each call (for example, a short prompt phrase for image generation rather than your full diary text). Per the contractual terms we’ve agreed to with these providers, your content sent through our API key is not used to train their models. However, you should also review each provider’s own terms before relying on this.
4. Apple Sign In
Sign in with Apple authenticates you to our Firebase backend. We receive a stable user ID and (optionally) an email address. If you select Apple’s “Hide My Email” option, we only ever see a relay email; we never see your real address.
5. What We Don’t Do
- We do not sell or share your data with advertisers or data brokers.
- We do not run third-party analytics or tracking SDKs (no Facebook, no Mixpanel, no Amplitude).
- We do not personalize ads — there are no ads.
- We do not access your diary content for any purpose other than delivering the app’s features to you.
6. Permissions We Request
- Microphone — to capture your voice recordings.
- Speech Recognition — to transcribe your voice into text on-device.
- Photo Library (Add Only) — only when you tap “Save to Photos” on a generated illustration.
We never ask for access we don’t need.
7. Your Rights and Controls
- Access and export. Use the in-app “Export my Book” feature to download your entire diary as PDF, EPUB, or DOCX.
- Edit and delete. Edit any entry inline; delete a single day or an entire period via the in-app menus.
- Account deletion. Menu → Delete Account permanently removes your diary text, images, animations, and account record from your device and from our cloud storage. This action is irreversible.
- Right to be forgotten / data requests. If you need anything beyond the in-app controls, email us at volostnovdm@gmail.com and we will respond within 30 days.
8. Children
Memerio is intended for users 13 and older. We do not knowingly collect content from children under 13. If we learn that we have, we will delete it.
9. Security
All traffic between the app, our proxy, and our backend providers uses HTTPS with modern TLS. Cloud storage at Firebase is access-controlled per-user with Firebase Security Rules — only the authenticated owner can read or write to their namespace. No system is perfectly secure; we encourage strong device passcodes and enabling iCloud account protections.
10. International Transfers
Memerio’s providers (Anthropic, OpenAI, DeepSeek, MiniMax, Google Firebase, Cloudflare) operate globally. Your content may be transferred to and processed in countries other than your country of residence, subject to those providers’ standard contractual safeguards.
11. Retention
We retain your diary content as long as your account is active or until you delete it. Backups of deleted data may persist in Firebase for up to 30 days before being permanently purged by Google’s rolling backup retention.
12. Changes to This Policy
If we make material changes, we will update the “Last updated” date above and surface a notice in the app on next launch. Your continued use of the Service after the update constitutes acceptance.
